DM74123N Dual Retriggerable One-Shot For Timing Pulses

DM74123N is used when a clean, repeatable pulse is more useful than another logic gate. It works well for switch debounce, power-on reset shaping, watchdog stretching, and timing delays for sequencing relays or control signals. DM74123N contains two retriggerable one-shot sections and runs from a 4.75 V to 5.25 V supply, making it a straightforward fit on 5V TTL control boards. Pulse width is set by external R and C components, so you can tune behavior without firmware changes. Route the timing network tightly around the pins and keep trigger traces away from noisy switching nodes to avoid false retriggers. When used as a reset shaper, confirm the downstream device’s required pulse polarity and duration. Request a quote for DM74123N.
