Presettable Counters

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.
