Overview
The 74HC7541D-Q100J, produced by Nexperia USA Inc., is an 8-bit buffer/line driver with Schmitt-trigger inputs and 3-state outputs. This device is part of the 74HC and 74HCT series, known for their high noise immunity and low power dissipation. It features two output enables (OE1 and OE2), allowing the outputs to assume a high-impedance OFF-state when either OE is HIGH. The Schmitt trigger inputs are designed to transform slowly changing input signals into sharply defined, jitter-free output signals, making it suitable for a wide range of applications.
