Description

The MC74HC4020AF, MC74C4020A is identical in pinout to the standard CMOS MC14020B. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL
outputs.

This device consists of 14 master−slave flip−flops with 12 stages brought out to pins. The output of each flip−flop feeds the next and the frequency at each output is half of that of the preceding one. Reset is asynchronous and active−high.

Features

• Output Drive Capability: 10 LSTTL Loads

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1 uA

• High Noise Immunity Characteristic of CMOS Devices

• In Compliance With JEDEC Standard No. 7A Requirements
