Data Sheet

1. General description
The 74HC7541; 74HCT7541 is an 8-bit buffer/line driver with Schmitt-trigger inputs and
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
. Schmitt trigger inputs transform slowly changing input signals into sharply defined
jitter-free output signals.
2. Features and benefits
