STP08CP05TTR

Overview

The STP08CP05TTR is a low-voltage, low-current power 8-bit shift register designed for LED panel displays. It features an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register. The device provides eight regulated current sources delivering 5-100 mA constant current to drive LEDs. Key electrical parameters include a supply voltage range of 3 V to 5.5 V, a maximum clock frequency of 30 MHz, and an output driving capability of 20 V. The part operates within a temperature range of -40°C to +125°C and is housed in a TSSOP-16 package.

Feature Summary

• Integrates an 8-bit serial-in, parallel-out shift register with an 8-bit D-type storage register for efficient data handling.
• Provides eight constant current output channels adjustable via an external resistor to control LED light intensity from 0% to 100%.
• Supports high-speed data transmission with a maximum clock frequency of 30 MHz and fast output current setup time.
• Features robust ESD protection rated at 2.5 kV HBM and 200 V MM, ensuring reliability in sensitive environments.

Applications

• LED panel displays
• Low-voltage microcontroller interfacing
• High-volume data transmission systems

Procurement Notes

Verify the specific suffix 'TTR' corresponds to the tape-and-reel packaging configuration as defined by STMicroelectronics. Confirm that the ordering code matches the exact TSSOP-16 package variant required for your PCB layout. Cross-reference the manufacturer's official datasheet to ensure compliance with RoHS and REACH standards before finalizing procurement specifications.

Selection Notes

Select this component when an 8-channel constant current sink is required for LED applications. It is suitable for designs needing compatibility with 3.3 V microcontrollers while supporting up to 5.5 V operation. Consider the exposed pad thermal efficiency if heat dissipation is a critical factor in the enclosure design compared to standard packages.
