Overview
The MC74VHC1G125DFT1G is an advanced high-speed CMOS noninverting 3-state buffer produced by onsemi. Fabricated with silicon gate CMOS technology, this device achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The internal circuit is composed of three stages, including a buffered 3-state output, which provides high noise immunity and stable output. This buffer is designed to interface 5V circuits to 3V circuits and offers protection when voltages up to 5.5V are applied, regardless of the supply voltage.
