SN74HC259DR TI Latches & Flip-Flops | 16-SOIC | 8-Bit Addressable Latch

Product Overview

The SN74HC259DR from Texas Instruments is an 8-bit addressable latch designed for general-purpose storage and data routing applications. It features three address inputs (A0–A2) that select one of eight latches for data entry, while the remaining latches retain their previous states. The device operates with a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial systems. Housed in a compact 16-SOIC package, it offers high noise immunity and low power consumption typical of HC CMOS logic.
