TPIC6B259DWG4

Overview

The TPIC6B259DWG4 is an 8-bit addressable latch manufactured by Texas Instruments, designed for high-voltage output control applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features inverting polarity with a propagation delay of 150 ns at 5 V. The device supports a single input line and eight output lines, housed in a SOIC-20 surface-mount package. It functions as a logic IC within the TPIC6B259 series, drawing a typical operating current of 300 uA. The component is rated for industrial temperatures from -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides 8-bit addressable latching capability for controlling multiple high-voltage loads simultaneously.
• Features integrated high-voltage outputs suitable for driving external devices directly.
• Supports serial data input for simplified interface connections with standard logic controllers.

Applications

• Industrial automation systems requiring precise load switching
• High-voltage LED matrix displays and lighting controls
• Solenoid and relay driver circuits in automotive or machinery environments

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your system's environmental specifications. Cross-reference the datasheet revision date to confirm electrical characteristics have not changed. Validate that the inverting polarity aligns with your control logic design.

Selection Notes

Select this component when an 8-bit latch with high-voltage output capability is required in a compact surface-mount form factor. Consider the 4.5 V to 5.5 V supply constraint and ensure your power delivery network supports this range. Evaluate the 150 ns propagation delay against your system's timing requirements. Compare the SOIC-20 package against available board space and thermal dissipation needs relative to through-hole alternatives like the PDIP variant.

Part Context

This part belongs to the TPIC6B259 family of addressable latches from Texas Instruments. It shares core functional architecture with other members of the series but differs in packaging and specific suffix designations. The DWG4 designation specifically identifies the SOIC-20 surface-mount package with green (RoHS compliant) construction. This places it within the broader category of high-voltage logic drivers used for interfacing low-voltage digital signals to higher voltage loads.

Replacement Considerations

The TPIC6B259N serves as a pin-compatible through-hole alternative within the same product family. Verify package compatibility before substitution, as the PDIP-20 housing differs physically from the SOIC-20. Functional parameters such as voltage ranges and channel counts remain consistent across these variants. Ensure thermal management strategies are adjusted appropriately for the different package types.
