Overview
The STP16CP596B1R is a low-voltage, 16-bit constant current LED sink driver manufactured by STMicroelectronics. It integrates a shift register and linear output drivers capable of sourcing up to 50mA per channel. The device operates on a supply voltage range of 3V to 5.5V with a maximum output voltage of 16V. It supports serial data input at frequencies up to 25MHz and features an operating temperature range from -40°C to 125°C. Packaged in a 24-DIP through-hole format, it serves as a direct replacement for legacy LED driver solutions.
Feature Summary
- Integrates a 16-bit shift register for serial data reception and storage.
- Provides linear constant current sinking capability for individual LED channels.
- Supports high-speed serial clock inputs for rapid data updating.
- Designed for robust operation across extended industrial temperature ranges.
Applications
- Static or multiplexed LED display panels
- LED indicator arrays in industrial control systems

Procurement Notes
Verify component status carefully, as this specific part number is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the 24-DIP package dimensions match your existing PCB footprint requirements. Check RoHS compliance documentation if environmental regulations apply to your final assembly process.
Selection Notes
Select this component when a 16-channel linear LED driver with integrated shift register functionality is required. It is suitable for designs needing moderate current levels around 50mA per output. Consider the through-hole mounting requirement and DIP package size during layout. Evaluate if the linear topology meets thermal dissipation needs compared to switching alternatives.
Part Context
This IC belongs to the STP16CP596 family of constant current LED sink drivers. These devices are designed to simplify LED driving circuits by combining data latching and current regulation in a single package. The family typically offers various output current options and packaging styles to suit different density and power requirements in display applications.
Replacement Considerations
Check for pin-compatible successors within the STP16CP series. Verify if newer variants offer improved efficiency or updated packaging while maintaining the same functional interface and electrical characteristics for seamless integration into existing designs.
