Overview
The STP08C596TTR is a monolithic, medium-voltage, low-current power 8-bit shift register designed for LED panel displays. It integrates an 8-bit serial-in parallel-out shift register feeding an 8-bit D-type storage register and eight regulated current sources. Operating supply voltage ranges from 4.5 V to 5.5 V. The device features linear dimming capabilities with output currents up to 120 mA per channel. It operates within a temperature range of -40°C to +125°C and is housed in a 16-TSSOP package.
Feature Summary
- Integrates 8-bit shift register and storage register for serial data input
- Provides eight regulated constant current outputs for LED driving
- Supports linear dimming functionality for display applications
Applications
- LED panel display systems
- Medium-voltage LED driver circuits
- Serial-to-parallel LED control interfaces
Procurement Notes
Verify the specific suffix 'TTR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 4.5 V to 5.5 V supply voltage range aligns with your system design. Ensure compatibility with the 16-TSSOP footprint during PCB layout. Check for any recent lifecycle status changes or alternative pin-compatible replacements if availability is constrained.
Selection Notes
Select this component when a monolithic solution combining shift register logic and constant current sinking is required. It is suitable for designs needing linear dimming control without external PWM drivers. Consider the 120 mA output capability against total LED load requirements. Verify that the medium-voltage rating meets the forward voltage sum of the LED strings in your application.
Part Context
This part belongs to the STP08C596 family of LED display drivers from STMicroelectronics. It serves as a specialized integrated circuit for managing LED arrays in signage and display panels. The device simplifies design by integrating data latching and current regulation into a single package, reducing component count compared to discrete solutions.
Replacement Considerations
Check for direct pin-to-pin replacements within the same manufacturer's portfolio if this specific reel variant is unavailable. Verify functional equivalence regarding current sourcing capabilities and voltage ratings before substituting.
