The CD74HC423M is a high-performance, dual retriggerable monostable multivibrator fabricated with silicon gate CMOS technology from Texas Instruments. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This device is designed to be triggered by an edge of a pulse and returns to its stable state after a delay determined by external components.

Product Description
The CD74HC423M device features two independent monostable multivibrators with separate reset and trigger inputs for each multivibrator. The triggers are buffered to lower the triggering pulse width requirement and allow for the use of longer trigger pulses. The reset inputs are active LOW and are used to immediately terminate the output pulse at any time during the pulse width, providing a high degree of control to the user.
With its wide supply voltage range, the CD74HC423M is suitable for applications in battery-operated devices, and its high noise immunity ensures reliable operation in industrial environments. The device's balanced propagation delay and transition times make it ideal for use in timing, pulse shaping, and signal processing applications.
Its SOIC-16 package allows for efficient use of PCB space, making it a preferred choice for compact, high-density electronic assemblies. The CD74HC423M is a versatile component that can be used in a variety of digital applications where precision timing and low power consumption are critical.
