TPIC6C595D

Overview

The TPIC6C595D is a monolithic high-voltage, medium-current power 8-bit shift register manufactured by Texas Instruments. It features an 8-bit serial-in parallel-out shift register and an 8-bit D-type storage register with separate clock inputs. The device utilizes low-side open-drain DMOS transistor outputs rated for 50 V with continuous sink current capabilities. Integrated voltage clamps provide protection against inductive transients. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a junction temperature range from -40°C to +125°C.

Feature Summary

• Integrated low-side open-drain DMOS outputs capable of driving high-voltage loads up to 50 V
• Built-in voltage clamping on output pins to protect against inductive transient spikes
• Separate clocking for shift register and storage registers allows data latching without disturbing the shift sequence
• Serial output pin enables cascading multiple devices for expanded I/O control

Applications

• Relay driver circuits requiring high-side or low-side switching
• Solenoid actuation systems for valves and mechanical locks
• High-voltage LED matrix displays and lighting arrays
• Industrial automation control panels for load management

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-16 surface-mount package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits to maintain device reliability and prevent thermal shutdown during high-current operation.

Selection Notes

Select this component for applications requiring direct drive of inductive or high-voltage loads without external transistors. The integrated clamping reduces bill-of-materials complexity compared to standard logic shift registers. Consider the SOIC-16 footprint constraints and verify thermal dissipation requirements if multiple channels are driven simultaneously at maximum current ratings.

Part Context

This part belongs to the TPIC6 series of power shift registers designed for robust industrial environments. Unlike standard logic families, it integrates power DMOS stages directly with CMOS logic control. The device simplifies interface design between microcontrollers and heavy loads, offering a compact solution for embedded systems needing isolated or high-power output control.
