Datasheet Summary
MC74HC161A, MC74HC163A
Presettable Counters
High- Performance Silicon- Gate CMOS
The MC74HC161A and HC163A are identical in pinout to the LS161 and LS163. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs.
The HC161A and HC163A are programmable 4- bit binary counters with asynchronous and synchronous reset, respectively.
Features
