STP16CPS05M

Overview

The STP16CPS05M is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It features a serial-in, parallel-out shift register feeding a D-type storage register. The output stage provides sixteen regulated current sources delivering 5 mA to 100 mA constant current. It supports a 3 V to 5.5 V supply, 20 V output driving capability, and a 30 MHz clock frequency. The device operates between -40°C and 125°C in a 24-SOP package.

Feature Summary

• Provides sixteen constant current output channels with adjustable intensity via external resistor
• Features auto power-saving mode that minimizes quiescent current when no active data is detected
• Supports high-speed data transmission with a maximum clock frequency of 30 MHz
• Capable of being driven directly by 3.3 V microcontrollers

Applications

• LED panel displays
• High data rate transmission systems
• Applications interfacing with 3.3 V microcontrollers

Procurement Notes

Verify component status as the STP16CPS05M is listed as obsolete and no longer manufactured. Confirm availability of parameter-equivalent substitutes such as the STP16CP05MTR or STP16CPC05MTR from STMicroelectronics. Ensure replacement parts match the required 24-SOP package and electrical specifications for your specific design implementation.

Selection Notes

Select this component for applications requiring low-voltage operation down to 3 V and precise LED brightness control. The integrated shift register and storage register simplify interface logic. Consider the 24-SOP package constraints and thermal requirements. Verify compatibility with 3.3 V logic levels if used with modern microcontrollers.
