TPIC6B259DW

Overview

The TPIC6B259DW is an 8-bit addressable latch manufactured by Texas Instruments, designed for high-voltage output applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features inverting outputs with a propagation delay of 150 ns at 5 V. The device supports a wide operating temperature range from -40°C to +125°C and is housed in a SOIC-20 surface-mount package.

Feature Summary

• Provides eight high-voltage outputs suitable for driving loads requiring elevated potential levels
• Features addressable latching functionality allowing independent control of each output state
• Includes built-in protection mechanisms such as thermal shutdown and clamp diodes on outputs

Applications

• Industrial automation systems requiring isolated high-side switching
• LED matrix displays and lighting control panels
• Solenoid and valve driver circuits in automotive or industrial environments

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to ensure compatibility with specific packaging or environmental certifications. Confirm that the SOIC-20 footprint matches your PCB design constraints. Check for any recent lifecycle notices regarding obsolescence or recommended replacements before finalizing procurement plans.

Selection Notes

Select this component when high-voltage capability combined with digital addressability is required. Ensure the system voltage remains within the 4.5 V to 5.5 V range to maintain specified performance. Consider the thermal management requirements given the +125°C maximum operating temperature rating and the power dissipation characteristics of the SOIC-20 package.

Part Context

This part belongs to the TPIC6B259 family of high-voltage addressable latches from Texas Instruments. It serves as a bridge between low-voltage digital logic and high-voltage analog loads. The DW variant specifically denotes the surface-mount SOIC-20 package option, distinguishing it from through-hole alternatives like the N suffix.

Replacement Considerations

Consult the official TI selection guide for direct pin-compatible substitutes within the same family. Verify electrical specifications and package dimensions before swapping with other manufacturers' components.
