Overview
The MC74VHC1GT126DF2G is a single gate noninverting 3-state buffer fabricated with silicon gate CMOS technology. It is designed to achieve high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS devices. This component is part of the VHC logic family and is suitable for a wide range of applications, including logic-level translation between different voltage levels.
The device features TTL-compatible inputs and CMOS-compatible outputs, making it versatile for interfacing between 5V and 3V circuits. It also includes input protection circuitry that allows overvoltage tolerance, preventing device destruction due to supply voltage and input/output voltage mismatches.
