TPIC6259DWRG4

Overview

The TPIC6259DWRG4 is an 8-bit addressable latch from Texas Instruments' Power Logic family, housed in a 20-pin SOIC package. It operates on a supply voltage range of 4.5V to 5.5V and supports output currents up to 250mA per channel. The device features standard outputs and functions as a D-type latch with one independent circuit. It is designed for industrial applications, operating within a temperature range of -40°C to 125°C.

Feature Summary

• Provides high-current drive capability suitable for direct load control
• Features addressable latching functionality for flexible data handling
• Designed for robust operation in demanding industrial environments

Applications

• Industrial LED driver circuits
• High-current load switching systems
• Automotive lighting control modules

Procurement Notes

Verify the complete part number including the suffix G4 to ensure compliance with RoHS standards and lead-free specifications. Confirm the SOIC-20 package type matches your PCB footprint requirements. Check the revision status to ensure the component is active and available for production. Validate that the 4.5V to 5.5V supply range aligns with your system power design.

Selection Notes

Select this component when high per-channel current capacity is required for driving loads directly without external transistors. The addressable latch architecture simplifies interface logic compared to standard shift registers. Ensure the thermal performance of the SOIC-20 package is sufficient for the expected duty cycle and ambient temperature conditions.

Part Context

This device belongs to the TPIC625x series of Power Logic addressable latches. It shares functional similarities with other members like the TPIC6B595 but offers specific current ratings and pin configurations tailored for high-power applications. The series is characterized by its ability to combine logic control with power output stages in a single integrated circuit.

Replacement Considerations

Direct substitutes include the TPIC6259DWR and TPIC6259DW variants. Verify pin compatibility and electrical specifications before replacing. The TPIC6B595 series may serve as an alternative if lower current requirements are acceptable.
