Presettable Counters
HighâPerformance SiliconâGate 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 4âbit binary counters with asynchronous and synchronous reset, respectively.
⢠Output Drive Capability: 10 LSTTL Loads
