Product Introduction

Overview

The 74LVC574AD,118 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs, manufactured by Nexperia (previously part of NXP Semiconductors). This device is designed for use in a wide range of digital logic applications, particularly in mixed 3.3 V and 5 V environments. It features a clock (CP) and output enable (OE) inputs, allowing for flexible control over the output states. The flip-flops store the state of their individual D-inputs on the LOW-to-HIGH clock transition, and a HIGH on the OE input causes the outputs to assume a high-impedance OFF-state without affecting the flip-flop states.
