Product Introduction

Overview

The SN74HC259DR, produced by Texas Instruments, is an 8-bit addressable latch designed for general-purpose storage applications in digital systems. This device is part of the 74HC series and is known for its versatility and reliability. It can function as a working register, serial-holding register, or as an active-high decoder or demultiplexer. The SN74HC259DR is capable of storing single-line data in eight addressable latches and can be configured in four distinct functional modes by controlling the clear (CLR) and enable (G) inputs.
