Description

The KK74AC161 is identical in pinout to the LS/ALS161, HC/HCT161. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.

The KK74AC161 is programmable 4-bit synchronous modulo-16 counter that feature parallel Load, asynchronous Reset, a Carry Output for cascading and count-enable controls.

The KK74AC161 is binary counter with asynchronous Reset.
