The MM74HC123AM from NATIONAL is a high-speed dual retriggerable monostable multivibrator utilizing advanced silicon-gate CMOS technology. It provides speeds comparable to low-power Schottky TTL while maintaining CMOS benefits like low power consumption and high noise immunity.
Key electrical features 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 device has Schmitt trigger inputs on A and B, allowing for slow rise and fall times. The output pulse width is determined by external RC components, following the formula PW = (REXT)(CEXT).
This multivibrator is retriggerable, meaning its output pulse can be extended by repeated triggering. All inputs are protected against static discharge. The MM74HC123AM is available in a 16-lead PDIP package suitable for through-hole mounting.
Applications include pulse generation, timing circuits, and waveform shaping where precise and stable pulse widths are required.
