SN74LS14 Description

Short technical summary and product information.

The SN74LS14 from Texas Instruments is a hex Schmitt-Trigger inverter IC designed for applications requiring high noise immunity and operation from very slow input edges. Each of the six inverters within the device provides a clean, jitter-free output signal even with slow input ramps due to its Schmitt-Trigger action, which creates different input threshold levels for positive-going and negative-going signals.

 

This component operates within a supply voltage range of 4.75V to 5.25V and features a typical propagation delay between 10ns and 50ns. The output current capabilities are 8mA for IOL (maximum) and -0.4mA for IOH (maximum). The device is suitable for a wide range of applications including HVAC gateways, robotic controls, and digital input modules for factory automation.

 

Available in various packages such as SOIC, SSOP, PDIP, CDIP, CFP, and LCCC, the SN74LS14 is designed for robust performance in industrial environments. Its temperature-compensated design ensures reliable operation across its specified temperature range of 0°C to 70°C.
