Dual Retriggerable Monostable Multivibrator

The IN74HC123A is identical in pinout to  the LS/ALS123. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

•  Outputs Directly Interface to CMOS, NMOS, and TTL
•  Operating Voltage Range:3.0 to6.0 V
•  Low InputCurrent:1.0 µA
•  High Noise Immunity Characteristic of CMOS Devices
