STP08CP05MTR

Overview

The STP08CP05MTR is a low-voltage, low-current power 8-bit shift register designed for LED panel displays. It integrates an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register with eight regulated constant current sources providing 5-100 mA output. The device supports a 3 V to 5.5 V supply, operates at a 30 MHz clock frequency, and guarantees a 20 V output driving capability. It features ESD protection of 2.5 kV HBM and 200 V MM, and is available 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 regulated constant current output channels adjustable via an external resistor for precise LED intensity control.
• Supports high-speed data transmission with a 30 MHz clock frequency and fast output current setup time.
• Features robust electrostatic discharge protection rated at 2.5 kV human body model and 200 V machine model.

Applications

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

Procurement Notes

Verify the specific suffix MTR indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the operating temperature range aligns with system requirements. Check for moisture sensitivity level specifications relevant to surface mount assembly processes. Validate pinout compatibility with existing PCB layouts.

Selection Notes

Select this component when designing LED display systems requiring low voltage operation down to 3 V. It is suitable for applications needing adjustable constant current outputs between 5 mA and 100 mA. Consider its thermal efficiency if using exposed pad packages. Ensure the 20 V output capability matches the series LED string voltage requirements. Verify interface compatibility with 3.3 V logic microcontrollers.
