Datasheet Summary
TECHNICAL DATA
Presettable Counters
High-Performance Silicon-Gate CMOS
The IN74HC161A is identical in pinout to the LS/ALS161. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The IN74HC161A is programmable 4-bit synchronous counter that feature parallel Load, asynchronous Reset, a Carry Output for cascading and count-enable controls. The IN74HC161A 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
- High Noise Immunity Characteristic of CMOS Devices
