The VHC14 is a high speed CMOS Hex Schmitt Inverter fabricated with silicon gate CMOS technology.
This document is a technical datasheet for the Fairchild Semiconductor 74VHC14, an advanced high-speed CMOS Hex Schmitt Inverter. The device utilizes silicon gate CMOS technology to achieve high-speed operation similar to Bipolar Schottky TTL while maintaining low power dissipation. It features hysteresis on inputs to transform slowly changing signals into sharply defined outputs and includes input protection for interfacing between 5V and 3V systems.
