Overview
The MC74VHC1GT125DF2G is a single gate noninverting 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 technology. This device is part of the 74VHC family, known for its advanced high-speed and low-power CMOS logic capabilities.
The MC74VHC1GT125 requires the 3-state control input (OE) to be set High to place the output into the high impedance state. It features TTL-compatible inputs and CMOS-compatible outputs, making it versatile for various logic level translations, such as from 3.0V CMOS logic to 5.0V CMOS logic or from 1.8V CMOS logic to 3.0V CMOS logic.
The device provides input and output protection structures, allowing it to handle voltages up to 7.0V regardless of the supply voltage, and ensuring safety during supply voltage mismatches, battery backup, and hot insertion scenarios.
