74HCT123DB118 Description

Short technical summary and product information.

The 74HCT123DB118 is a dual retriggerable monostable multivibrator with reset, manufactured by NXP Semiconductors. This component is designed for flexibility, allowing the output pulse width to be programmed by external components and extended through retriggering. It operates within a wide supply voltage range of 2.0 V to 6.0 V and is specified for operation from -40 °C to +125 °C.

 

Key features include CMOS low power dissipation, high noise immunity, and Schmitt-trigger action on most inputs, making it tolerant to slower input rise and fall times. The device supports DC triggering from active HIGH or active LOW inputs and offers a direct reset function to terminate the output pulse. Its retriggerable nature allows for very long pulses with up to a 100% duty factor.

 

The 74HCT123DB118 is available in a 16-SSOP surface mount package. Its design includes clamp diodes on the inputs, enabling the use of current-limiting resistors for interfacing with voltages exceeding VCC. This makes it suitable for various timing and pulse generation applications in electronic circuits.
