Product Introduction

Overview

The SN74HC573AN is an octal transparent D-type latch produced by Texas Instruments. This component is part of the HC logic family and is designed to operate within a wide voltage range of 2 V to 6 V. It features 3-state outputs, making it suitable for driving highly capacitive or relatively low-impedance loads. The device is particularly useful in applications such as buffer registers, I/O ports, bidirectional bus drivers, and working registers.
