Overview
The MC74HC541ADWG, produced by onsemi, is an octal 3-state noninverting buffer/line driver/line receiver. This device is part of the high-performance silicon-gate CMOS family and is designed to be used in various bus-oriented systems, including 3-state memory address drivers, clock drivers, and other similar applications. It is identical in pinout to the LS541 and is compatible with Standard CMOS outputs, as well as LSTTL outputs with external pull-up resistors. The MC74HCT541A variant can also serve as a level converter for interfacing TTL or NMOS outputs to high-speed CMOS inputs.
