74HC259DB,118

Latches Overview

The Nexperia 74HC259DB,118 is an 8-bit addressable latch in a SO-16 (SOT109-1) package. It operates on a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features four modes: addressable latch, memory, demultiplexer/decoder, and reset. It includes clamp diodes for input protection and meets JESD 78 Class II Level B latch-up standards.

Latches Feature Summary

• Supports serial-to-parallel conversion with random addressable data entry
• Provides common reset input and individual storage bit outputs
• Includes built-in ESD protection exceeding specified JEDEC thresholds
• Features inputs compatible with CMOS logic levels

Latches Applications

• Serial-to-parallel data conversion circuits
• Addressable memory storage modules
• 3-to-8 active HIGH decoding applications
• Demultiplexing signal routing systems

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature rating. Confirm RoHS compliance status through official documentation before integration. Ensure design margins align with the absolute maximum ratings provided in the datasheet to prevent permanent damage during operation.

Latches Selection Notes

Select this component when an 8-bit latching function with independent addressing is required within a wide voltage range. The SO-16 package suits surface-mount designs needing standard spacing. Verify that the CMOS input levels match the driving source logic family specifications for reliable interface performance.

Latches Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It functions as an 8-bit addressable latch, distinct from standard flip-flops by allowing individual bit access via address lines. The device integrates decoding logic to select specific storage elements within the latch array.

Latches Replacement Considerations

The 74HCT259D,118 serves as a functional substitute offering TTL-compatible input levels while maintaining identical pinout and latch functionality.
