Product Introduction

Overview

The 74HC7540D,112 is an 8-bit inverting buffer/line driver with Schmitt-trigger inputs and 3-state outputs, produced by Nexperia USA Inc. This device is part of the 74HC/74HCT family and is designed to provide high noise immunity and low power dissipation. It features two output enables (OE1 and OE2) that allow the outputs to assume a high-impedance OFF-state when activated. The Schmitt trigger inputs help in transforming slowly changing input signals into sharply defined, jitter-free output signals.
