IN74HC161A中文资料IKSEMICON数据手册PDF规格书

The IN74HC161A 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 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
