TPIC6B259DWRG4

Overview

The TPIC6B259DWRG4 is an 8-bit addressable latch manufactured by Texas Instruments, belonging to the TPIC6B259 series. It features a single circuit with eight output lines and one input line, 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 specifications include a propagation delay of 150 ns at 5 V, an inverting polarity, 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 high-voltage outputs designed to drive loads directly without external buffering components.
• Includes integrated protection mechanisms such as latch-up immunity and thermal shutdown for reliable operation.

Applications

• Industrial automation systems requiring direct drive of solenoids or relays
• LED matrix displays and lighting control panels
• Consumer appliance interface circuits

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with lead-free and RoHS standards. Confirm the SOIC-20 package variant matches the design footprint. Check the datasheet for specific handling requirements regarding electrostatic discharge sensitivity during assembly and storage procedures.

Selection Notes

Select this component when an 8-bit latch with high-voltage output capability is required in a compact surface-mount form factor. Ensure the system voltage remains within the 4.5 V to 5.5 V range. Consider the -40°C to +125°C operating temperature range for industrial or automotive environments where standard commercial grade parts may be insufficient.

Part Context

This device is part of the TPIC6B259 family of high-voltage latch ICs from Texas Instruments. It serves as a bridge between low-voltage logic controllers and higher-power peripheral devices. The DWR package designation indicates a wide-body SOIC format optimized for thermal performance and PCB space efficiency in dense electronic assemblies.

Replacement Considerations

Consult official substitution guides for equivalent high-voltage latches. Verify pin compatibility and electrical characteristics before replacing with alternative manufacturers' parts.
