What are the key features of CD74HC423MG4?
- Dual retriggerable monostable multivibrator allows pulse extension by re-triggering during the output pulse, enabling versatile timing control in a single package
- High-speed CMOS HC/UH logic family provides low power consumption with high noise immunity and CMOS-compatible input thresholds
- 16-pin SOIC surface-mount package (JESD-30 R-PDSO-G16) with RoHS-compliant lead-free construction for modern board designs
What is CD74HC423MG4 used for?
The CD74HC423MG4 is commonly used in digital timing circuits, pulse stretching, and debounce applications in industrial control systems, microcontroller peripherals, and communication interfaces. Its retriggerable design allows it to generate extended output pulses as long as trigger signals continue to arrive within the current timing window, which is valuable in watchdog timer circuits and power-on reset generators. The dual independent channels enable two separate timing functions in a single compact package, reducing board area in space-constrained designs.

Frequently Asked Questions
What is the CD74HC423MG4 and what does retriggerable mean?
The CD74HC423MG4 is a dual retriggerable monostable multivibrator, meaning each of its two independent one-shot circuits can restart its output pulse timing if a new trigger arrives before the current pulse ends. This retriggerable property is essential for pulse extension, missing-pulse detection, and watchdog timer implementations.
How is the output pulse width set on the CD74HC423MG4?
The output pulse width of the CD74HC423MG4 is determined by an external resistor and capacitor (RC) network connected to the Rx and Cx pins of each channel. Larger RC values produce longer output pulses, allowing designers to set timing from nanoseconds to milliseconds with appropriate component selection.
What logic family does the CD74HC423MG4 belong to and what are its voltage requirements?
The CD74HC423MG4 belongs to the HC/UH high-speed CMOS logic family, which typically operates over a supply voltage range of 2V to 6V. HC-family devices offer low quiescent current, high noise immunity, and output drive up to 5.2mA (Iol max 0.0052A), making them compatible with both 3.3V and 5V digital systems.
What package does the CD74HC423MG4 use?
The CD74HC423MG4 is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, as indicated by JESD-30 code R-PDSO-G16. The 'M' in the suffix denotes the SOIC package variant, which is a standard surface-mount format widely supported by PCB assembly processes.
Is the CD74HC423MG4 RoHS compliant?
Yes, the CD74HC423MG4 carries JESD-609 code e4 and Pbfree Code: Yes, confirming it is a lead-free, RoHS-compliant component. The 'G4' suffix in the part number also indicates Texas Instruments' green product designation, meaning halogen-free and environmentally compliant construction.
