Overview
The STP16C596XTTR is a monolithic, medium-voltage, low-current power 16-bit shift register designed for LED panel displays. It functions as a constant current LED sink driver with 16 outputs. The device operates within an input voltage range of 4.5V to 5.5V and supports output voltages up to 16V or 20V depending on specific configuration. It features a high-level output current capability of 1mA and a low-level sink current of approximately 120mA. The component is housed in a HTSSOP-24 package and operates across a temperature range of -40°C to +125°C.
Feature Summary
- Monolithic 16-bit shift register architecture optimized for LED panel display applications
- Constant current LED sink driver functionality ensuring uniform LED brightness
- Medium-voltage operation supporting high-output voltage requirements for series LED strings
Applications
- LED panel displays
- Dot matrix displays
- Signage systems requiring constant current sinking
Procurement Notes
Verify the exact suffix (XTTR) against the manufacturer's latest datasheet to confirm packaging type and tape/reel specifications. Ensure compatibility with system voltage levels, specifically the 4.5V to 5.5V input range. Check for end-of-life status or alternative recommendations from STMicroelectronics, as some variants may be discontinued. Confirm RoHS compliance requirements for your specific manufacturing process.
Selection Notes
Select this component when designing LED displays requiring integrated shift register and constant current drive capabilities in a single package. It is suitable for applications needing medium-voltage output handling and wide operating temperature ranges. Consider the HTSSOP-24 package size for space-constrained PCB layouts. Evaluate the 120mA sink current against the total LED load requirements per channel.
Part Context
The STP16C596 belongs to STMicroelectronics' family of LED display drivers. It integrates shift register logic with power output stages, simplifying the design of large-scale LED matrices. This integration reduces component count compared to discrete solutions combining logic ICs and linear drivers. The device is part of the broader STP series focused on efficient LED illumination control.
Replacement Considerations
STP16CP05XTTR is a related variant within the same product family offering similar 16-bit shift register functionality with potentially different current characteristics.
