TPIC6259DWG4

Overview

The TPIC6259DWG4 is an 8-bit addressable latch from Texas Instruments, designed for power logic applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features eight outputs capable of driving high-current loads. The device utilizes a serial input interface with separate clock and latch lines for data control. It is housed in a 20-pin SOIC package and supports operating temperatures from -40°C to +125°C.

Feature Summary

• Provides independent 8-bit latching capability for direct load control
• Features serial data input with dedicated clock and latch inputs
• Designed for high-current output drive requirements

Applications

• Industrial motor control systems
• High-power LED lighting arrays
• Solenoid and relay driver circuits

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance against current manufacturer specifications. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental conditions. Check for any recent obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when an 8-bit parallel output solution is required from a serial interface. It is suitable for applications needing higher current handling than standard logic families. Consider the thermal performance of the SOIC-20 package under continuous load. Evaluate if the 5V supply voltage aligns with your system architecture.

Part Context

This part belongs to the TPIC6259 family of power logic addressable latches. It serves as a bridge between low-voltage digital controllers and high-power external loads. The device simplifies wiring by reducing the number of control lines needed for multiple outputs compared to individual drivers.

Replacement Considerations

The TPIC6B259DWG4 is a documented alternative within the same product family.
