MM74HC123AMTC Description

Short technical summary and product information.

The MM74HC123AMTC from ON Semiconductor is a high-speed CMOS monostable multivibrator designed for precise timing applications. It features two independent retriggerable one-shot circuits, each with both negative and positive edge-triggered inputs, and a clear input for resetting.

 

Key electrical characteristics include a typical propagation delay of 25 ns and a wide operating power supply range from 2V to 6V. The device offers low quiescent current (80 µA max) and low input current (1 µA max), making it suitable for low-power designs. The output pulse width is determined by external RC components, following the formula PW = (REXT)(CEXT).

 

This multivibrator is available in a 16-TSSOP surface mount package, designed for efficient board space utilization. The A and B inputs feature Schmitt trigger characteristics, allowing for slow input rise and fall times. All inputs are protected against static discharge.

 

Applications include pulse generation, delay circuits, and waveform shaping where precise and stable timing is required. The retriggerable nature allows for extending the output pulse duration by repeated triggering.
