TPIC6A596DWG4

Overview

The TPIC6A596DWG4 is an eight-bit shift register with registered outputs and open-drain drivers, belonging to the Texas Instruments TPIC6A series. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 100MHz. The device features serial input and parallel output capabilities, designed for driving high-current loads such as LEDs or relays. It is housed in a 20-pin SOIC package.

Feature Summary

• Eight-bit serial-in parallel-out shift register architecture
• Open-drain output drivers capable of sourcing significant current
• Registered parallel outputs for stable signal holding
• High-speed serial clock operation

Applications

• LED matrix displays
• Relay driver circuits
• Industrial control systems
• General-purpose I/O expansion

Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free and RoHS compliance status according to manufacturer documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with the target application environment. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Selection Notes

Select this component when high-current sinking capability is required for parallel loads driven by a serial interface. Consider the open-drain output nature for level shifting requirements. Evaluate the power dissipation characteristics if multiple outputs are active simultaneously. Compare against standard logic families if lower current drive is sufficient.

Part Context

This part belongs to the TPIC6A family of high-current shift registers from Texas Instruments. It shares functional similarities with other members like the TPIC6B595 but offers specific drive characteristics suited for direct load connection without external transistors. The series is commonly used in embedded systems requiring expanded digital outputs.

Replacement Considerations

Check for pin-compatible alternatives within the same TI family. Verify that substitute parts maintain the same current rating and voltage limits. Ensure logical functionality remains identical for seamless integration.
