SN74123N Description

Short technical summary and product information.

The Texas Instruments SN74123N is a dual retriggerable monostable multivibrator IC designed for logic applications. It belongs to the TTL technology family and offers two independent circuits for versatile timing control.

 

Key electrical characteristics include a propagation delay of 22 ns and a supply current of 800µA. The device supports a voltage range of 4.75 V to 5.25 V, with output current capabilities of 16mA (IOL max) and -0.8mA (IOH max). The operating temperature range is specified from 0°C to 70°C, making it suitable for various environmental conditions.

 

This component is housed in a 16-PDIP package, designed for through-hole mounting. The SN74123N features Schmitt-trigger inputs, enhancing its reliability in noisy environments. Its retriggerable nature allows for very long output pulses, up to 100% duty cycle, with an overriding clear function to terminate the output pulse.

 

Applications for the SN74123N include pulse generation, timing circuits, and delay functions where precise and controllable pulse widths are required. Its standard speed and robust design make it a reliable choice for many digital systems.
