74HC540; 74HCT540 Octal buffer/line driver; 3-state; inverting Rev. 6 — 19 October 2021 Product data sheet 1. General description The 74HC540; 74HCT540 is an 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. 2.
