Overview
The 74HC125DTR2G is a quad 3-state noninverting buffer integrated circuit produced by ON Semiconductor. Although this specific part is now obsolete and no longer manufactured, it was designed to provide four independent buffer gates with 3-state outputs. Each buffer has a separate enable pin that, when driven with a high logic level, places the corresponding output in the high impedance state. This component was part of ON Semiconductor's comprehensive portfolio of logic devices aimed at various applications including automotive, communications, computing, and more.
