Overview
The 74HC7541D,112 is an octal Schmitt trigger buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the 74HC/74HCT family and is designed to provide high noise immunity and low power dissipation. The device features Schmitt-trigger inputs, which transform slowly changing input signals into sharply defined, jitter-free output signals. It also includes two output enables (OE1 and OE2) that allow the outputs to be set to a high-impedance OFF-state when either enable is HIGH.
