SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

The MC54/74HC160A and HC162A are identical in pinout to the LS160

and LS162, respectively. The device inputs are compatible with standard

CMOS outputs; with pullup resistors, they are compatible with LSTTL

outputs.

J SUFFIX

CERAMIC PACKAGE

CASE 620–10

The HC160A and HC162A are programmable BCD counters with

asynchronous and synchronous Reset inputs, respectively.
