Octal buffer/line driver; 3-state
Rev. 1 — 19 June 2014
Product data sheet
1. General description
The 74HC541-Q100; 74HCT541-Q100 is an octal non-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
that enable 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.
