Overview
The STP16CPP05PTR is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It functions as a constant current LED sink driver with an operating supply voltage range of 3V to 5.5V and a maximum output voltage of 20V. The device features 16 outputs capable of delivering up to 40mA per channel in constant current mode. It operates at a clock frequency of 30MHz and utilizes a 24-QSOP surface-mount package.
Feature Summary
- Monolithic 16-bit serial-in shift register architecture optimized for LED panel applications
- Integrated constant current sink driver capability for uniform LED brightness control
- Low-voltage operation compatible with standard digital logic levels
- High-speed serial interface supporting data rates up to 30MHz
Applications
- LED matrix display panels
- Dot matrix signage systems
- Low-voltage LED indicator arrays
Procurement Notes
Verify the specific suffix PTR against the manufacturer's official datasheet to confirm the 24-QSOP package configuration and tape-and-reel shipping format. Ensure compatibility with system voltage requirements within the 3V to 5.5V range. Cross-reference the part number with authorized distributors to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when designing LED displays requiring integrated constant current sinking and serial data shifting in a compact form factor. The 40mA output current per channel suits standard LED indicators. Consider the 24-QSOP package dimensions for PCB layout constraints. Verify that the 30MHz clock speed meets the refresh rate requirements of the target display application.
Part Context
This part belongs to the STP16CP05 series from STMicroelectronics, which includes variants such as STP16CPP05TTR. These devices are engineered specifically for driving LED panels where space and power efficiency are critical. The series provides a consolidated solution for data latching and current regulation, reducing the need for external components in display driver circuits.
Replacement Considerations
Check for direct pin-compatible substitutes within the same STP16CP05 family, such as STP16CPP05TTR, ensuring identical electrical characteristics and package type. Verify that any alternative maintains the 40mA constant current specification and 30MHz operational frequency.
