These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3080/MAX3081/MAX3082 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3083/MAX3084/MAX3085 offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver. These transceivers typically draw 375µA of supply current when unloaded, or when fully loaded with the drivers disabled. All devices have a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus. The MAX3082/MAX3085/MAX3088 are intended for halfduplex communications, while the MAX3080/MAX3081/ MAX3083/MAX3084/MAX3086/MAX3087 are intended for full-duplex communications. The MAX3089 is selectable between half-duplex and full-duplex operation. It also features independently programmable receiver and transmitter output phase via separate pins.

These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled (see Fail-Safe section). The MAX3080/ MAX3081/MAX3082 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps (see Reduced EMI and Reflections section). The MAX3083/MAX3084/MAX3085 offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/ MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a three-state driver. The MAX3082/MAX3085/MAX3088 are half-duplex transceivers, while the MAX3080/MAX3081/MAX3083/ MAX3084/MAX3086/MAX3087 are full-duplex transceivers. The MAX3089 is selectable between half- and full-duplex communication by driving a selector pin high or low, respectively. All of these parts operate from a single +5V supply. Drivers are output short-circuit current limited. Thermal shutdown circuitry protects drivers against excessive power dissipation. When activated, the thermal shutdown circuitry places the driver outputs into a highimpedance state. Receiver Input Filtering The receivers of the MAX3080–MAX3085, and the MAX3089 when operating in 115kbps or 500kbps mode, incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differential signals that have very slow rise and fall times. Receiver propagation delay increases by 20% due to this filtering.

Driver DC Test Load Fail-Safe The MAX3080 family guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver threshold between -50mV and -200mV. If the differential receiver input voltage (A-B) is greater than or equal to -50mV, RO is logic high. If A-B is less than or equal to -200mV, RO is logic low. In the case of a terminated bus with all transmitters disabled, the receiver’s differential input voltage is pulled to 0V by the termination. With the receiver thresholds of the MAX3080 family, this results in a logic high with a 50mV minimum noise margin. Unlike previous fail-safe devices, the -50mV to -200mV threshold complies with the ±200mV EIA/TIA-485 standard. MAX3089 Programming The MAX3089 has several programmable operating modes. Transmitter rise and fall times are programmable between 2500ns, 750ns, and 25ns, resulting in maximum data rates of 115kbps, 500kbps, and 10Mbps, respectively. To select the desired data rate, drive SRL to one of three possible states by using a three-state driver, by connecting it to VCC or GND, or by leaving it unconnected. For 115kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. For 500kbps operation, drive SRL high or connect it to VCC. For 10Mbps operation, drive SRL low or connect it to GND. SRL can be changed during operation without interrupting data communications. Occasionally, twisted-pair lines are connected backward from normal orientation. The MAX3089 has two pins that invert the phase of the driver and the receiver to correct for this problem. For normal operation, drive Figure 6. Receiver Enable/Disable Timing Test Load TXP and RXP low, connect them to ground, or leave them unconnected (internal pulldown). To invert the driver phase, drive TXP high or connect it to VCC. To invert the receiver phase, drive RXP high or connect it to VCC. Note that the receiver threshold is positive when RXP is high. The MAX3089 can operate in full- or half-duplex mode. Drive the H/F pin low, leave it unconnected (internal pulldown), or connect it to GND for full-duplex operation, and drive it high for half-duplex operation. In fullduplex mode, the pin configuration of the driver and receiver is the same as that of a MAX3080 (Figure 4). In half-duplex mode, the receiver inputs are switched to the driver outputs, connecting outputs Y and Z to inputs A and B, respectively. In half-duplex mode, the internal full-duplex receiver input resistors are still connected to pins 11 and 12. Applications Information 256 Transceivers on the Bus The standard RS-485 receiver input impedance is 12kΩ (one-unit load), and the standard driver can drive up to 32 unit loads. The MAX3080 family of transceivers have a 1/8-unit-load receiver input impedance (96kΩ), allowing up to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices and/or other RS-485 transceivers with a total of 32 unit loads or less can be connected to the line. Reduced EMI and Reflections The MAX3080–MAX3085, and MAX3089 with SRL = VCC or unconnected, are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. Figure 14 shows the driver output waveform and its Fourier analysis of a 20kHz signal transmitted by a MAX3086/MAX3087/MAX3088, and MAX3089 with SRL = GND.

Figure 15 shows the same signal displayed for a MAX3083/ MAX3084/MAX3085, and MAX3089 with SRL = VCC), transmitting under the same conditions. Figure 15’s high-frequency harmonic components are much lower in amplitude, compared with Figure 14’s, and the potential for EMI is significantly reduced. Figure 16 shows the same signal displayed for a MAX3080/ MAX3081/MAX3082, and MAX3089 with SRL = unconnected, transmitting under the same conditions. Figure 16’s high-frequency harmonic components are even lower. In general, a transmitter’s rise time relates directly to the length of an unterminated stub, which can be driven with only minor waveform reflections. The following equation expresses this relationship conservatively: Length = tRISE / (10 x 1.5ns/ft) where tRISE is the transmitter’s rise time. For example, the MAX3080’s rise time is typically 1320ns, which results in excellent waveforms with a stub length up to 90 feet. A system can work well with longer unterminated stubs, even with severe reflections, if the waveform settles out before the UART samples them. ______________________________________________________________________________________ 17 元器件交易网www.cecb2b.com MAX3080–MAX3089 Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422 Transceivers RO R RE DE DI D MAX3080/MAX3081/MAX3083/ MAX3084/MAX3086/MAX3087/ MAX3089 (FULL DUPLEX) A 120Ω B DATA IN Z 120Ω Y DATA OUT DI VA - VB RO MAX3080/3089 FIG-18 5V/div 1V/div 5V/div NOTE: RE AND DE ON MAX3080/MAX3083/MAX3086/MAX3089 ONLY.

In shutdown, the devices typically draw only 1nA of supply current. RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown. Enable times tZH and tZL in the Switching Characteristics tables assume the part was not in a lowpower shutdown state. Enable times tZH(SHDN) and tZL(SHDN) assume the parts were shut down. It takes drivers and receivers longer to become enabled from low-power shutdown mode (tZH(SHDN), tZH(SHDN)) than from driver/receiver-disable mode (tZH, tZL). Driver Output Protection Two mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention. The first, a foldback current limit on the output stage, provides immediate protection against short circuits over the whole common-mode voltage range (see Typical Operating Characteristics). The second, a thermal shutdown circuit, forces the driver outputs into a high-impedance state if the die temperature becomes excessive. Line Length vs. Data Rate The RS-485/RS-422 standard covers line lengths up to 4000 feet. For line lengths greater than 4000 feet, use the repeater application shown in Figure 17. Figures 18, 19, and 20 show the system differential voltage for the parts driving 4000 feet of 26AWG twistedpair wire at 110kHz into 120Ω loads. Typical Applications The MAX3082/MAX3085/MAX3088/MAX3089 transceivers are designed for bidirectional data communications on multipoint bus transmission lines. Figures 21 and 22 show typical network applications circuits. These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 17. To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possible. The slew-rate-limited MAX3082/MAX3085, and the two modes of the MAX3089, are more tolerant of imperfect termination. 18 ______________________________________________________________________________________ MAX3080–MAX3089 元器件交易网www.cecb2b.com Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422 Transceivers MAX3080/3089 FIG-19 MAX3080/3089 FIG-20 DI 5V/div DI 5V/div VA - VB 1V/div VA - VB 1V/div RO 5V/div 2µs/div Figure 19.
