Presettable Counter
High-Speed Silicon-Gate CMOS
The IN74AC161 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 IN74AC161 is programmable 4-bit synchronous modulo-16
counter that feature parallel Load, asynchronous Reset, a Carry Output
for cascading and count-enable controls.
The IN74AC161 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
