双可再触发单稳多谐振荡器与重置 Dual retriggerable monostable multivibrator with reset
**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**
■ All inputs have a Schmitt-trigger action
■ Inputs accept voltages higher than VCC
■ DC triggered from active HIGH or active LOW inputs
■ Retriggerable for very long pulses up to 100 % duty factor
■ Direct reset terminates output pulse
■ For 74AHC123A only: operates with CMOS input levels
■ For 74AHCT123A only: operates with TTL input levels
