Overview
The MC74VHC50DTR2G, produced by onsemi, is a high-speed CMOS hex buffer fabricated with silicon gate CMOS technology. This device is part of the MC74VHC50 series and is designed to achieve high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS technology. The MC74VHC50DTR2G is particularly useful for level conversion between 3.3 V and 5.0 V systems, thanks to its full 5.0 V CMOS level output swings.
