SN7414

The Texas Instruments SN7414 is a hex Schmitt-Trigger inverter IC designed for applications requiring high noise immunity and reliable operation with slow input signal edges. Each of the six independent inverters within the SN7414 functions to invert the input signal, but the Schmitt-Trigger action provides distinct threshold levels for positive-going and negative-going signals, ensuring clean, jitter-free output.

This device operates with a supply voltage range of 4.75-V to 5.25-V and is constructed using TTL technology. Key electrical characteristics include a low level output current (IOL) of 16 mA and a high level output current (IOH) of -0.8 mA. The device exhibits a high speed with a propagation delay (tpd) between 10-50 ns and a maximum supply current of 60000 µA.

The SN7414 is suitable for a wide range of industrial applications, including HVAC gateways, robotic controls, and digital input modules for factory automation. It is available in various package types such as SOIC, SSOP, PDIP, CDIP, CFP, and LCCC, supporting different mounting requirements.

With its improved line-receiving characteristics and temperature compensation, the SN7414 is engineered to provide stable performance even with the slowest input ramps, making it a robust choice for digital signal conditioning.
