STP16DPS05TTR

Overview

The STP16DPS05TTR is a low-voltage, low-power 16-bit shift register designed for LED panel displays. It features a serial input and parallel output architecture with an integrated 16-bit D-type storage register. The device provides sixteen constant current sinks capable of delivering 20 mA to 100 mA per channel, regulated by an external resistor. It supports a supply voltage range of 3 V to 5.5 V, operates at clock frequencies up to 30 MHz, and includes open-circuit and short-circuit detection capabilities. The component is housed in a TSSOP-24 package.

Feature Summary

• Integrated 16-bit constant current sink drivers with adjustable output current via external resistance
• Built-in diagnostic circuitry for detecting open circuits and short circuits on output lines
• High-speed 30 MHz serial data interface supporting rapid transmission rates
• Enhanced thermal performance provided by the exposed pad TSSOP-24 package

Applications

• LED matrix display panels
• Dot matrix LED indicators
• Low-voltage microcontroller interfacing systems
• Portable electronic devices requiring efficient LED driving

Procurement Notes

Verify the specific suffix 'TTR' against the manufacturer's official datasheet to confirm the exact packaging configuration, such as cut tape or reel specifications. Ensure that the selected variant matches the required operating temperature range and RoHS compliance status for your specific manufacturing process. Cross-reference the ordering information with the latest STMicroelectronics documentation to avoid discrepancies in package type or moisture sensitivity levels.

Selection Notes

Select this component when designing systems that require precise constant current regulation for multiple LEDs without external driver ICs. It is suitable for applications needing high brightness control through PWM or analog dimming via the OE/DM2 pin. Consider the 3V minimum supply voltage for compatibility with modern low-power logic families. Evaluate the thermal requirements of the TSSOP-24 package if driving currents approach the upper limit of the 100 mA specification.

Part Context

This part belongs to the STP16DP series of LED display drivers from STMicroelectronics. It is functionally related to the STP16C/L596 but offers enhanced diagnostic features and improved thermal characteristics. The series is designed to replace older generation drivers while providing better integration for serial data handling and error detection in complex LED arrays.

Replacement Considerations

Publicly confirmed substitute part numbers include STP16CPPS05XTTR and STP16DPPS05XTTR. Verify electrical compatibility and pinout alignment before substitution.
