SN74LS123NSR Description

Short technical summary and product information.

The SN74LS123NSR from Texas Instruments is a dual retriggerable monostable multivibrator designed for logic applications. This component operates within a supply voltage range of 4.75V to 5.25V, with a typical supply current of 20000µA. It offers a propagation delay of 28 ns and supports a wide operating temperature range from 0°C to 70°C.

 

This device is housed in a 16-SOIC surface mount package, making it suitable for various PCB designs. The SN74LS123NSR features two independent circuits and a push-pull output type. Its retriggerable functionality allows for very long output pulses, up to 100% duty cycle, and it includes an overriding clear to terminate the output pulse. The input type is bipolar, and it is part of the LS technology family.

 

Key electrical characteristics include an IOL (max) of 8mA and an IOH (max) of -0.4mA. The monostable logic type and its retriggerable feature make it versatile for timing circuits and pulse generation applications. The component is designed for standard speed operations.
