54HC4020 - 14-Bit Asynchronous Binary Counters

Datasheet Summary

Description

The ’HC4020 devices are 14-stage binary ripple-carry counters that advance on the negative-going edge of the clock pulse.

The counters are reset to zero (all outputs low) independently of the clock (CLK) input when the clear (CLR) input goes high.

Features

Wide operating voltage range of 2 V to 6 V.
Outputs can drive up to 10 LSTTL loads.
Low power consumption, 80-µA max ICC.
Typical tpd = 12 ns.
±4-mA output drive at 5 V.
Low input current of 1 µA max 2.
