High–Performance Silicon–Gate CMOS

The MC74HC161A and HC163A are identical in pinout to the

LS161 and LS163. The device inputs are compatible with standard

CMOS outputs; with pullup resistors, they are compatible with

LSTTL outputs.

The HC161A and HC163A are programmable 4–bit binary counters

with asynchronous and synchronous reset, respectively.
