Overview
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.
