Overview
The MC74HCT541ADWR2G is an octal non-inverting buffer/line driver/line receiver produced by onsemi. This device is part of the HC/HCT family of high-performance silicon-gate CMOS logic ICs. It is designed to be used in various bus-oriented systems, including 3-state memory address drivers, clock drivers, and other similar applications. The MC74HCT541ADWR2G is identical in pinout to the LS541 and features inputs and outputs on opposite sides of the package, along with two ANDed active-low output enables. This makes it highly versatile for interfacing TTL or NMOS outputs to high-speed CMOS inputs.
