1. General description
The 74HC540-Q100; 74HCT540-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
