Hex Schmitt Inverter

The TC74LVX14F/ FN/ FT is a high-speed CMOS HEX SCHMITT INVERTER fabricated with silicon gate CMOS technology. Designed for use in 3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.

This device is suitable for low-voltage and battery operated systems.

Pin configuration and function are the same as the TC74LVX04 but the inputs have hysteresis and with its schmitt trigger function, the TC74LVX14 can be used as a line receivers which will receive slow input signals.

An input protection circuit ensures that 0 to 5.5V can be applied to the input pins without regard to the supply voltage.

This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
