Download the TC74HC123AP datasheet PDF. This datasheet also covers the TC74HC123 variant, as both devices belong to the same dual retriggerable monostable multivibrator family and are provided as variant models within a single manufacturer datasheet.

General Description

(1) Stand-by state The external capacitor (Cx) is fully charged to VCC in the stand-by state.

triggering, the QP and QN transistors which are connected to the Rx/Cx node are in the off state.

ual Retriggerable Monostable Multivibrator The TC74HC123A is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. There are two trigger inputs, A input (negative edge), and B input (positive edge). These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. This device may also be triggered by using CLR input (positive edge). After triggering, the output stays in a MONOSTABLE state for a time period determined by the external
