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
