74AHC259D,112

Latches Overview

The NXP USA Inc. 74AHC259D,112 is a high-speed Si-gate CMOS device specified in compliance with JEDEC standard No. 7-A. It functions as an 8-bit addressable latch designed for general-purpose storage applications in digital systems. The component combines demultiplexer and 8-bit latch capabilities, providing serial-to-parallel conversion and random data entry. It features active HIGH outputs (Q0 to Q7), an active LOW common reset (MR), and an active LOW enable input (LE). The device operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C.

Latches Feature Summary

• Combines demultiplexer and 8-bit latch functionality
• All inputs feature Schmitt-trigger actions
• Inputs accept voltages higher than VCC
• Easily expandable architecture

Latches Applications

• General purpose storage applications in digital systems
