Frequently Asked Questions

What is the supply voltage range for the CD74HC423M?

The CD74HC423M operates over a supply voltage range of 2V to 6V, making it compatible with both 3.3V and 5V digital logic systems. This wide range allows flexible integration into various embedded and industrial designs.

What does retriggerable mean for the CD74HC423M monostable multivibrator?

Retriggerable means that while the output pulse is active, a new trigger input will restart the timing cycle and extend the output pulse width. This feature is useful in applications requiring pulse extension or timeout reset logic, such as watchdog timers and debounce circuits.

What package type does the CD74HC423M come in and what are its pin count?

The CD74HC423M is housed in a 16-Pin SOIC (Small Outline Integrated Circuit) surface-mount package, identified by JESD-30 code R-PDSO-G16. This compact package is suitable for high-density PCB designs and automated SMT assembly processes.

What are typical applications for the CD74HC423M?

The CD74HC423M is commonly used in pulse width generation, signal debouncing, one-shot timing circuits, clock gating, and sequential event control. It is suitable for industrial automation, consumer electronics, communication equipment, and embedded microcontroller systems requiring precise timing delays.

Are there alternative parts compatible with the CD74HC423M?

Compatible alternatives include the SN74HC423 and CD74HCT423 from Texas Instruments, as well as equivalents from other manufacturers such as the 74HC423 series. The HCT variant supports TTL-compatible input thresholds while maintaining the same dual retriggerable monostable functionality.
