Overview
The 74HCT540D-Q100J is an 8-bit inverting buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74HCT series, which is known for its high-speed Si-gate CMOS technology and compatibility with low power Schottky TTL (LSTTL) devices. 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 in various digital circuit applications. The device includes clamp diodes on the inputs, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
