TPIC6259DW

Overview

The TPIC6259DW is an 8-bit addressable latch manufactured by Texas Instruments, designed for power logic applications. It features a single circuit with eight output lines housed in a SOIC-20 surface-mount package. The device 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. Key electrical characteristics include an inverting polarity, a propagation delay of 150 ns at 5 V, and a quiescent current of 300 uA.

Feature Summary

• Provides 8-bit data storage with individual addressability for precise control of multiple outputs.
• Integrates high-current sink drivers suitable for direct connection to loads such as LEDs or relays.
• Features serial input capability to reduce microcontroller pin usage through shift register functionality.

Applications

• LED matrix display systems requiring individual pixel control
• Industrial relay driver circuits for load switching
• Automotive lighting control modules

Procurement Notes

Verify the specific suffix (e.g., DW) against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration. Cross-reference the revision level to guarantee compatibility with existing design specifications and regulatory requirements.

Selection Notes

Select this component when designing systems that require high-current sinking capabilities combined with serial data input. The wide operating temperature range makes it suitable for harsh environments. Consider the SOIC-20 footprint for PCB layout constraints and ensure the supply voltage remains within the specified 4.5 V to 5.5 V window for reliable operation.

Part Context

This part belongs to the TPIC6B259 family of power logic addressable latches. It shares functional similarities with the TPIC6259 but may differ in specific drive strength or internal protection features. It serves as a bridge between low-voltage digital logic and higher-power analog loads, simplifying interface design in complex electronic systems.

Replacement Considerations

The TPIC6259DWG4 is a verified lead-free variant of this component. Verify pinout compatibility before substitution. Other members of the TPIC6A259 series may offer alternative drive characteristics but require schematic review.
