TPIC6595DW

Overview

The TPIC6595DW is an 8-bit shift register with latch and driver capabilities manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features open-drain outputs capable of handling voltages up to 50.0V. The device utilizes serial-to-serial/parallel data transfer with a propagation delay of 650ns. It is housed in a surface-mount SOIC-20 package, supports a single circuit configuration, and functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates high-voltage open-drain output drivers for direct load control
• Provides serial input conversion to parallel output via internal latch
• Operates with standard logic-level supply voltages while supporting higher load voltages

Applications

• LED matrix driving systems
• Industrial relay control interfaces
• High-side or low-side load switching applications

Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-20 surface mount package variant. Ensure compatibility with the required 4.5V to 5.5V supply rails and confirm that the open-drain output characteristics align with the target load voltage requirements. Cross-reference the manufacturer datasheet for thermal performance specifications under intended operating conditions.

Selection Notes

Select this component when an 8-bit serial interface is needed to drive high-voltage loads directly without external transistors. The wide operating temperature range makes it suitable for industrial environments. Consider the SOIC-20 footprint constraints and ensure the board layout accommodates the thermal dissipation needs of the open-drain outputs during continuous operation.

Part Context

This part belongs to the TPIC series of high-voltage shift registers designed by Texas Instruments. These devices are engineered to simplify the interface between low-voltage logic controllers and high-voltage loads. The series typically includes variants with different packaging options such as PDIP and SOIC, catering to both through-hole and surface-mount assembly requirements.

Replacement Considerations

Check for pin-compatible alternatives within the same TPIC family, such as the TPIC6B595 series, which may offer similar functionality but potentially different packaging or minor electrical characteristic variations.
