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 (OE
1 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
V
CC
.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
