74HC123D Description

Short technical summary and product information.

The 74HC123D is a dual retriggerable monostable multivibrator with reset, manufactured by NXP Semiconductors. It is designed for applications requiring precise pulse generation and timing control.

 

This device operates across a wide supply voltage range of 2.0 V to 6.0 V, offering flexibility in various system designs. It features Schmitt-trigger action on its inputs, providing high noise immunity and tolerance to slower input rise and fall times. The output pulse width can be programmed using external components and extended through retriggering. A direct reset input is available to terminate the output pulse.

 

The 74HC123D is available in a 16-SOIC surface mount package, suitable for automated assembly processes. Its operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions. The component offers 2 independent circuits for versatile timing applications.
