TPIC6B259DWR

Overview

The TPIC6B259DWR is an 8-bit addressable latch manufactured by Texas Instruments, housed in a 20-pin SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. The device features one input line and eight output lines with inverting polarity. Electrical characteristics include a propagation delay of 150 ns at 5 V and a typical quiescent current of 300 µA.

Feature Summary

• Provides 8-bit data storage with serial-to-parallel conversion capabilities for addressable control applications.
• Features inverting logic polarity to manage signal states effectively within digital circuits.
• Designed for robust operation across extended industrial temperature ranges.

Applications

• Addressable LED lighting systems requiring individual channel control
• Industrial automation interfaces for managing discrete output signals
• Consumer electronics utilizing serial data expansion

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 4.5 V to 5.5 V supply voltage limits and thermal management requirements for the -40°C to +125°C operational range.

Selection Notes

Select this component when an 8-bit latching solution with serial interface is required in a compact surface-mount form factor. The SOIC-20 package offers a balance between pin count and board space efficiency. Consider the inverting output characteristic during logic design to ensure correct signal alignment with downstream loads or controllers.

Part Context

This part belongs to the TPIC6B259 series of addressable latches from Texas Instruments. It serves as a bridge between low-power digital logic and higher-current load control, offering a dedicated storage function distinct from shift registers. The series is engineered for reliability in environments demanding stable data retention and consistent switching performance.

Replacement Considerations

The TPIC6B259DWRG4 is a verified lead-free variant within the same product family. Verify pinout and electrical specifications match before substitution. Other members of the TPIC6B259 series may offer different packaging options but share core functional attributes.
