Overview
The 74HC541D,653 is an octal non-inverting buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the 74HC series and is designed to provide high performance and reliability in various electronic applications. The device 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-oriented systems.
