What are the key features of CD74HC423M96G4?
- Dual retriggerable one-shot channels allow continuous output pulse extension while trigger input is active
- HC CMOS family operates from 2 V to 6 V supply, bridging 3.3 V and 5 V system voltages
- External RC network sets pulse width from nanoseconds to seconds, providing flexible timing without a microcontroller
What is CD74HC423M96G4 used for?
CD74HC423M96G4 is used for pulse-width generation and signal stretching in digital control systems, industrial safety circuits, and communication interfaces. Its retriggerable architecture allows the output pulse to be extended as long as a repetitive trigger is present, making it suitable for watchdog-style timeout circuits and missing-pulse detectors. The dual-channel configuration enables two independent timing functions on a single 16-pin SOIC device, saving board space in sequencing and handshaking circuits.

Frequently Asked Questions
How does the retriggerable feature of CD74HC423M96G4 differ from a non-retriggerable monostable, and when does it matter?
In CD74HC423M96G4, each new trigger pulse restarts the output timing cycle before the previous pulse ends, extending the output high period as long as triggers arrive faster than the RC timeout. A non-retriggerable device ignores triggers during the timing window, which can miss fast burst events in communication bus arbitration or encoder pulse monitoring applications.
How is the output pulse width set on CD74HC423M96G4, and what component values yield a 1 ms pulse?
Pulse width is determined by an external resistor and capacitor connected to the Cx and Rx/Cx pins, with the period approximately equal to 0.28 × R × C for the HC423 family. To achieve a 1 ms pulse, a 10 kΩ resistor combined with a 357 nF capacitor (or the nearest standard 330 nF value for approximately 0.92 ms) satisfies the timing requirement at 5 V supply.
Which industrial applications benefit most from using both channels of CD74HC423M96G4 simultaneously?
Applications such as 2-wire safety relay sequencers and dual-axis motor encoder input conditioners require 2 independent one-shot timers, making the dual-channel CD74HC423M96G4 in a 16-pin SOIC more cost-effective than two separate single-channel devices. Each channel can be programmed to a different pulse width using separate RC networks on the 50 pF-rated output pins.
