SN54LS14J

The SN54LS14J is a hex Schmitt-Trigger inverter from Texas Instruments, designed for applications requiring high noise immunity and operation from slow input ramps. Each of the six independent inverters within the device functions to provide a clean, jitter-free output signal.

This component operates with a supply voltage range of 4.5V to 5.5V and features a push-pull output type. The input type is Schmitt-Trigger, which allows for different threshold levels for positive-going and negative-going signals, enhancing its ability to handle noisy or slow input signals. The technology family is LS (Low-power Schottky).

With a military rating and an operating temperature range of -55°C to 125°C, the SN54LS14J is suitable for demanding environments. It is available in various package types including CDIP (J), CFP (W), and LCCC (FK). The high speed characteristic, with a typical propagation delay between 10-50ns, makes it suitable for various digital logic applications.

Each circuit in the SNx414 and SNx4LS14 series functions as an inverter. The Schmitt-Trigger action provides hysteresis, meaning the input threshold levels for switching are different for rising and falling signals. This temperature-compensated design ensures reliable performance even with very slow input signal transitions.
