Overview
The MC74VHC1GT125DF1G is a single gate noninverting buffer fabricated with silicon gate CMOS technology, produced by onsemi. This device achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS technology. It features a 3-state control input (OE(bar)) that allows the output to be placed into a high impedance state when set High. The input is compatible with TTL-type input thresholds, and the output has a full 5V CMOS level output swing. This buffer is designed to operate over a wide voltage range from 2.0V to 5.5V, making it versatile for various applications.
