TPIC6C596DR

Overview

The TPIC6C596DR is an automotive-grade, 8-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 buffered open-drain outputs capable of driving high-current loads up to 150 mA per channel. The device is housed in a 16-pin SOIC package with a propagation delay of 80 ns. Designed for harsh environments, it supports operating temperatures from -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards for durability in vehicle applications.
• High-current open-drain outputs provide direct drive capability for external loads without additional buffering.
• Shift register architecture enables efficient serial data conversion to parallel output for control systems.

Applications

• Automotive lighting control modules
• Industrial load switching interfaces
• General-purpose driver circuits in harsh environments

Procurement Notes

Verify the specific suffix DR indicates the tape-and-reel packaging format when sourcing components. Confirm that the AEC-Q100 qualification aligns with your project's automotive reliability requirements. Ensure the open-drain output configuration matches your load interface design, as this affects pull-up resistor selection. Cross-reference the SOIC-16 footprint dimensions during PCB layout to guarantee mechanical compatibility.

Selection Notes

Select this component when high current drive capability is required directly from a logic-level shift register. The automotive qualification makes it suitable for under-hood or exterior vehicle electronics where temperature extremes are common. Consider the open-drain output nature for voltage level shifting needs. Compare against standard industrial variants if automotive certification is not strictly necessary for cost optimization.

Part Context

This part belongs to the TPIC6C596 series of shift registers designed for high-side or low-side switching applications. It integrates eight D-type flip-flops with serial-to-parallel conversion capabilities. The series is engineered to simplify the control of multiple high-power devices using minimal microcontroller pins, reducing system complexity and board space requirements.
