74HC540N Datasheet PDF - NXP

●The 74HC540N is a 8-bit inverting Buffer/Line Driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

● Input CMOS level

● Complies with JEDEC standard no. 7A
