The 74VHCT14AFT is an advanced high speed CMOS SCHMITT INVERTER fabricated with silicon gate C 2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
Pin configuration and function are the same as the 74VHC04FT but the inputs have hysteresis and with its schmitt trigger function, the 74VHCT14AFT can be used as a line receivers which will receive slow input signals.
The input voltage are compatible with TTL output voltage
This device may be used as a level converter for interfacing 3.3 V to 5 V system
