The DS78C20 and DS88C20 are high performance, dual differential,CMOS compatible line receivers for both balancedand unbalanced digital data transmission. The inputs arecompatible with EIA and Federal Standards.Input specifications meet or exceed those of the popularDS7820/DS8820 line receiver, and the pinout is identical.A response pin is provided for controlling sensitivity to inputnoise spikes with an external capacitor. Each receiver includesa 180W terminating resistor, which may be used optionallyon twisted pair lines. The DS78C20 is specified overa −55°C to +125°C operating temperature range, and theDS88C20 over a 0°C to +70°C range.
