74HCT7541-Q100
Octal Schmitt trigger buffer/line driver; 3-state
Rev. 1 — 24 March 2014
Product data sheet
1. General description
The 74HC7541-Q100; 74HCT7541-Q100 is an 8-bit buffer/line driver with Schmitt-trigger
inputs and 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
. Schmitt trigger inputs transform slowly changing input signals into
sharply defined jitter-free output signals.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits
