Presettable Counter High-Speed Silicon-Gate CMOS

The IN74ACT161 is identical in pinout to the LS/ALS161, HC/HCT161. The IN74ACT161 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS Inputs.

The IN74ACT161 is programmable 4-bit synchronous modulo-16 counter that feature parallel Load, asynchronous Reset, a Carry Output for cascading and count-enable controls.

The IN74ACT161 is binary counter with asynchronous Reset.
