The 74VHC14 is an advanced high speed CMOS SCHMITT INVERTER fabricated with silicon gate C2MOS
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 74VHC04 but the inputs have hysteresis and with its schmitt
trigger function, the 74VHC14 can be used as a line receivers which will receive slow input signals.
An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.
