Overview
The 74HC541PW/C4118 is an octal non-inverting buffer/line driver with 3-state outputs, manufactured by NXP USA Inc. (now part of Nexperia). This device is designed to provide high-performance buffering and line driving capabilities in a variety of electronic systems.
It features two output enables (OE1 and OE2), allowing for flexible control over the output states. A HIGH on either OE1 or OE2 causes the outputs to assume a high-impedance OFF-state, which is useful for bus applications.
