Overview
The MC74VHCT50ADR2G is a hex 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. The internal circuit is composed of three stages, including a buffered output, which provides high noise immunity and stable output. The device is compatible with TTL-type input thresholds and offers full 5 V CMOS level output swings, making it suitable for interfacing 5 V circuits to 3 V circuits.
