74HC259DB,112

Latches Overview

The NXP USA Inc. 74HC259DB,112 is an 8-bit addressable latch from the HC logic family, 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/decoder, and reset. It includes clamp diodes for input protection and meets JEDEC standards JESD8C and JESD7A.

Latches Feature Summary

• Supports serial-to-parallel conversion with random addressable data entry via A0-A3 inputs
• Provides combined functionality as an 8-channel active HIGH decoder or demultiplexer
• Includes common reset input and ESD protection exceeding 2000 V HBM and 1000 V CDM

Latches Applications

• Memory expansion systems requiring individual bit storage
• Serial-to-parallel data conversion interfaces
• Active HIGH decoding and demultiplexing circuits

Latches Procurement Notes

Verify the specific ordering suffix '118' against the manufacturer's current documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the SOT109-1 SO16 package outline and temperature range requirements for your design environment.

Latches Selection Notes

Select this component when an 8-bit addressable latch with wide voltage compatibility is required. The HC series offers CMOS-level input compatibility. Consider the 74HCT259 variant if TTL-level input signals are present in the system architecture.

Latches Part Context

This part belongs to the Nexperia 74HC/HCT259 product family, which provides 8-bit addressable latching capabilities. The family encompasses various package options including TSSOP and QFN variants, all sharing identical functional characteristics and electrical specifications across different physical form factors.

Latches Replacement Considerations

Compatible substitutes include the 74HC259PW (TSSOP16) and 74HC259BQ (DHVQFN16) from the same manufacturer. Verify that any replacement maintains the SO16 footprint or requires appropriate PCB layout adjustments.
