TECHNICAL DATA

KK74AC161

Presettable Counter

High-Speed Silicon-Gate CMOS

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.

•

Outputs Directly Interface to CMOS, NMOS, and TTL

Operating Voltage Range: 2.0 to 6.0 V

Low Input Current: 1.0 µA; 0.1 µA @ 25° C

High Noise Immunity Characteristic of CMOS Devices

Outputs Source/Sink 24 mA
