The TC74HC161A and 163A are high speed CMOS BINARY

PRESETTABLE COUNTERs fabricated with silicon gate C²MOS

technology.

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The CK input is active on the rising edge. Both LOAD and

CLR inputs are active on low logic level.

TC74HC161AF, TC74HC163AF

Presetting of their IC’s is synchronous to the rising edge of CK.

The clear function of the TC74HC163A is synchronous to CK,

while the TC74HC161A is cleared asynchronously.

Two enable inputs (ENP and ENT) and CO are provided to

enable easy cascading of counters, which facilitates easy

implementation of n-bit counters without using external gates.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
