CD74HC259M

Latches Overview

The CD74HC259M is an 8-bit addressable latch manufactured by Harris Corporation using high-speed silicon gate CMOS technology. It features a single data input, eight independent outputs, three address inputs, and common enable and clear controls. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 16-SOIC package.

Latches Feature Summary

• Provides individual latching for eight distinct output lines controlled by binary addressing
• Maintains stored data states independently when the device is deselected via the enable input
• Includes protection circuits designed to guard against static discharge and transient excess voltage

Latches Applications

• Data storage in digital systems requiring specific address selection
• Memory expansion modules utilizing address decoding
• Display drivers needing individual segment control

Latches Procurement Notes

Verify component authenticity through manufacturer documentation or authorized channels. Confirm package integrity and pin alignment prior to assembly. Ensure environmental compliance requirements match project specifications. Review datasheet electrical characteristics for operational limits. Validate supplier credentials to mitigate counterfeit risks.

Latches Selection Notes

Select this component for applications requiring precise data retention at specific addresses. Consider the wide operating voltage range for flexible power supply designs. Evaluate the surface-mount package suitability for automated assembly processes. Compare propagation delays against system timing requirements.

Latches Part Context
