TPIC6A596DW

Overview

The TPIC6A596DW is an eight-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features open-drain outputs capable of driving high-current loads up to 350 mA per channel. The device utilizes a standard three-wire serial interface for data input and clocking. It is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package with a wide operating temperature range spanning from -40 °C to +125 °C.

Feature Summary

• High current drive capability with individual output channels rated at 350 mA
• Open-drain output configuration suitable for various load types
• Serial-to-parallel data conversion using a standard three-wire interface
• Wide operating temperature range supporting industrial environments

Applications

• Driving high-power LEDs or lighting arrays
• Controlling solenoid valves and relays
• Industrial automation control panels
• Motor driver interfacing circuits

Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 package variant when sourcing. Confirm RoHS compliance status as indicated on the official datasheet. Ensure the selected component matches the required thermal performance specifications for your application environment. Cross-reference the manufacturer's part number directly to avoid counterfeit components.

Selection Notes

Select this component when high-output current is required without external transistors. Compare against standard logic shift registers if lower current loads are sufficient. Consider the open-drain nature of the outputs for pull-up resistor requirements. Evaluate the SOIC-20 package constraints against available PCB space and thermal dissipation needs.

Part Context

This device belongs to the TPIC6A59x family of power shift registers designed for direct load driving. It integrates level shifting and protection features typically found in discrete solutions. The series provides a compact alternative to separate shift registers and driver transistors, simplifying circuit design for medium-to-high power applications.

Replacement Considerations

Check for pin-compatible alternatives within the same TI family that may offer different packaging options. Verify equivalent current ratings and voltage tolerances before substituting with components from other manufacturers.
