STP16CPC05PTR

Overview

The STP16CPC05PTR 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. Sixteen regulated current sources provide adjustable constant current from 5 mA to 100 mA per channel. The device supports a supply voltage range of 3 V to 5.5 V and guarantees a 20 V output driving capability. It operates with a maximum clock frequency of 30 MHz and includes ESD protection rated at 2 kV HBM and 200 V MM.

Feature Summary

• Provides sixteen constant current output channels with adjustable brightness via an external resistor
• Features high-speed data transmission capability with a maximum clock frequency of 30 MHz
• Ensures robust operation through integrated electrostatic discharge protection mechanisms
• Supports direct interfacing with 3.3 V microcontrollers due to low voltage power supply requirements

Applications

• LED panel displays
• High data rate transmission systems
• Microcontroller-based lighting control interfaces

Procurement Notes

Verify the specific package variant when ordering, as the PTR suffix indicates SSOP-24 packaging. Confirm that the required output current range and voltage levels align with the system design specifications. Ensure compatibility with the intended serial interface protocols. Check for any recent product change notifications regarding manufacturing updates or compliance status changes before finalizing procurement plans.

Selection Notes

Select this component for applications requiring precise constant current regulation across multiple LED channels. Consider its suitability for designs needing high-speed serial data input and low-voltage operation. Evaluate the thermal performance within the specified operating temperature range. Compare against alternative packages if board space constraints differ from the SSOP-24 form factor.
