General description
The 74AHC123A; 74AHCT123A are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
Features
â All inputs have a Schmitt-trigger action
â Inputs accept voltages higher than VCC
â DC triggered from active HIGH or active LOW inputs
â Retriggerable for very long pulses up to 100 % duty factor
â Direct reset terminates output pulse
â For 74AHC123A only: operates with CMOS input levels
â For 74AHCT123A only: operates with TTL input levels
