SN74AHC123ADR Description

Short technical summary and product information.

The SN74AHC123ADR is a dual retriggerable monostable multivibrator IC manufactured by Texas Instruments. Designed for a wide operating voltage range of 2V to 5.5V, this device offers flexibility in various applications.

 

Key features include Schmitt-trigger circuitry on the inputs, which allows for reliable operation even with slow input transition rates. The multivibrator is edge-triggered and retriggerable, enabling the generation of very long output pulses. An overriding clear function is also present to terminate output pulses.

 

This component is available in a 16-SOIC package, suitable for surface mount applications. It has a typical propagation delay of 7.5 ns and supports output currents of 8mA (IOL max) and -8mA (IOH max). The operating temperature range is from -40°C to 85°C.

 

The SN74AHC123ADR is designed for applications requiring precise pulse generation and timing control.
