Overview
The MC74VHC14DTR2 is a high-speed CMOS Schmitt inverter produced by onsemi. Fabricated with silicon gate CMOS technology, this device achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS technology. The MC74VHC14 is designed to operate within a voltage range of 2.0 V to 5.5 V, making it versatile for various applications. It features six independent Schmitt trigger inverters, each with hysteresis, which enhances noise immunity and stability in output signals. This component is particularly useful as a line receiver for slow input signals and as a level converter between 3.3 V and 5.0 V systems.
