SL74HC161
Presettable Counters
High-Performance Silicon-Gate CMOS
The SL74HC161 is identical in pinout to the LS/ALS161. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The SL74HC161 is programmable 4-bit synchronous counter that feature parallel Load, asynchronous Reset, a Carry Output for cascading and count-enable controls. The SL74HC161 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.
