SN74AHC123ADR TI Multivibrators

The SN74AHC123A is a dual retriggerable monostable multivibrator with Schmitt-trigger inputs, operating from 2V to 5.5V supply. It provides two independent monostable devices with three trigger inputs: A (active-low), B (active-high), and clear (active-low). Output pulse width is set by external timing components (R and C). The device features retriggerable operation, allowing pulse extension. Propagation delay is 7.5ns typical at 5V. Selection is ideal for precision timing and pulse extension in digital systems. Applications include pulse shaping, time delay generation, missing pulse detection, debouncing circuits for mechanical switches, and pulse width stretching in industrial controls and consumer electronics.
