TPIC6B595N

Overview

The TPIC6B595N is an 8-bit shift register with a DMOS logic family, housed in a 20-pin PDIP package for through-hole mounting. It operates within a supply voltage range of 4.5V to 5.5V and supports a bidirectional serial-to-parallel data flow. The device functions across an extended temperature range from -40°C to +125°C. It integrates transient protection features and includes a serial output for cascading applications.

Feature Summary

• Integrates open-drain DMOS outputs capable of sinking continuous current for driving medium-power loads
• Includes built-in voltage clamping on output pins to provide protection against inductive transients
• Features a serial input that shifts data into an 8-bit storage register before transferring to the output buffer

Applications

• Relay driver circuits requiring high-side or low-side switching control
• Solenoid actuation systems for industrial automation
• Cascaded LED matrix displays utilizing serial data expansion

Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 through-hole package variant rather than surface-mount options like DWR or DWG4. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the application environment remains within the specified -40°C to +125°C operating temperature limits to maintain device reliability.

Selection Notes

Select this component when through-hole assembly is required for power shift registers. It is suitable for designs needing integrated inductive load protection without external flyback diodes. Consider alternative packages if PCB space constraints favor surface-mount technology over the larger DIP footprint.

Part Context

This part belongs to the Texas Instruments TPIC6B595 series, which provides high-voltage, medium-current power shift registers. The series is designed for systems requiring higher load power capabilities, combining standard logic shift register functionality with robust power output stages.
