74HC259D,653

Latches Overview

The Nexperia 74HC259D,653 is an 8-bit addressable latch housed in a 16-lead SO plastic small outline package (SOT109-1). 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, and reset. Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Latches Feature Summary

• Supports serial-to-parallel conversion and random addressable data entry
• Functions as a combined demultiplexer and 8-bit latch
• Includes ESD protection compliant with ANSI/ESDA/JEDEC standards

Latches Applications

• Memory mode storage applications
• 3-to-8 active HIGH decoding
• Demultiplexing circuits

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the component status remains current before finalizing procurement plans. Ensure compatibility with existing design specifications regarding voltage levels and operating temperature ranges.

Latches Selection Notes

Select this component when an 8-bit addressable latch or demultiplexer is required within the 74HC logic family. Verify that the 2.0 V to 6.0 V supply voltage range aligns with system requirements. Consider the 16-lead SO package dimensions for PCB layout constraints.

Latches Part Context

This part belongs to the 74HC series of CMOS logic devices manufactured by Nexperia. It is functionally related to other 8-bit latches and decoders but offers specific addressable control via three address inputs. The D suffix indicates the SO16 package variant.

Latches Replacement Considerations

Cross-reference with other 74HC259 variants from different manufacturers if pinout compatibility is required. Verify electrical characteristics such as propagation delay and output drive current against original specifications.
