STP16CP05TTR

Overview

The STP16CP05TTR 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 independent constant current output channels for uniform LED brightness
• Enables brightness control via an external resistor adjusting the output current range
• Supports high-speed data transmission with a maximum clock frequency of 30 MHz
• Features robust electrostatic discharge protection for reliable operation in sensitive environments

Applications

• LED panel displays
• High brightness LED arrays
• Systems interfacing with 3.3 V microcontrollers

Procurement Notes

Verify the specific suffix XTTR or TTR against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and ESD protection levels for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing LED systems requiring precise current regulation across multiple channels without external drivers. It is suitable for applications needing compatibility with 3.3 V logic levels and high-speed serial data input. Consider the 20 V output capability for series LED configurations and verify thermal management requirements for the chosen current settings.
