The MM74HC123AM is a dual retriggerable monostable multivibrator utilizing advanced silicon-gate CMOS technology. It offers speeds comparable to low power Schottky TTL circuitry while maintaining the low power and high noise immunity characteristic of CMOS circuits.
This device features both negative (A) and positive (B) transition triggered inputs, either of which can serve as an inhibit input. A clear input is also included, which resets the one-shot when taken low. The MM74HC123AM is retriggerable, meaning its outputs can be triggered repeatedly to extend the pulse duration.
Key electrical specifications include a typical propagation delay of 25 ns, a wide power supply range from 2V to 6V, and low quiescent current of 80 µA maximum. The output pulse width is determined by the formula PW = (REXT)(CEXT), with a typical pulse range from 400 ns to infinity. Part-to-part variation is typically ±5%.
The MM74HC123AM is available in various package types including PDIP, SOIC, SOP, and TSSOP. All inputs are protected against static discharge damage.
