Overview
The MC74VHC1G125DF1G is an advanced high-speed CMOS 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. The internal circuit is composed of three stages, including a buffered 3-state output, which provides high noise immunity and stable output. This device is suitable for interfacing 5V circuits to 3V circuits and offers protection when voltages up to 5.5V are applied, regardless of the supply voltage.
