MM54HC4017/MM74HC4017Decade Counter/Divider with 10 Decoded OutputsGeneral Des criptionThe MM54HC4017/MM74HC4017 is a 5-stage Johnsoncounter with 10 decoded outputs that utilizes advanced silicon-gate CMOS technology. Each of the decoded outputs isnormally low and sequentially goes high on the low to hightransition of the clock input. Each output stays high for oneclock period of the 10 clock period cycle. The CARRY outputtransitions low to high after OUTPUT 9 goes low, andcan be used in conjunction with the CLOCK ENABLE tocascade several stages. The CLOCK ENABLE input disablescounting when in the high state. A RESET input isalso provided which when taken high sets all the decodedoutputs low except output 0.The MM54HC4017/MM74HC4017 is functionally and pinoutequivalent to the CD4017BM/CD4017BC. It can driveup to 10 low power Schottky equivalent loads. All inputs areprotected from damage due to static discharge by diodesfrom VCC and ground.FeaturesY Wide power supply range: 2±6VY Typical operating frequency: 30 MHzY Fanout of 10 LS-TTL loadsY Low quiescent current: 80 mA (74HC Series)Y Low input current: 1.0 mA
