TLC6989DYYR

Specialized Overview

The TLC6989DYYR is an LED display driver manufactured by Texas Instruments, designed to bridge SPI controllers with the TLC698x matrix series. It operates within a supply voltage range of 2.5 V to 5.5 V and draws a maximum power current of 3.1 mA. The device supports data transmission rates up to 20 MHz via SPI or Continuous Clock Serial Interface (CCSI). It features an internal oscillator for continuous clock generation and includes diagnostic capabilities such as CRC, fault output, UVLO, and open-drain fault pins. Packaged in a SOT-23-THN-14 format, it functions across temperatures from -40°C to +85°C.

Specialized Feature Summary

• Provides SPI-compatible connection to control TLC698x devices using standard SPI controllers
• Integrates an internal oscillator to generate continuous clocks required by the TLC698x series
• Includes diagnostic features such as CRC, fault output, and UVLO for system reliability

Specialized Applications

• SPI-compatible connection for TLC6983 devices
• SPI-compatible connection for TLC6984 devices
• Matrix LED display systems requiring CCSI interface compliance

Specialized Procurement Notes

Verify the specific package variant and manufacturer lot codes upon receipt to ensure alignment with design specifications. Confirm RoHS compliance status through official documentation before integration into regulated assemblies. Cross-reference the ordering suffix with the datasheet to validate pinout and electrical characteristics match the intended application requirements.

Specialized Selection Notes

Select this component when interfacing standard SPI microcontrollers with TLC698x LED matrices. Ensure the host controller supports the required 20 MHz data rate and CCSI timing constraints. Verify that the 2.5 V to 5.5 V operating voltage range matches the system power rails. Consider the SOT-23-THN-14 package dimensions for PCB layout compatibility.

Specialized Part Context

This device belongs to the TLC6989 series, serving as a bridge between SPI controllers and the broader TLC698x family of LED drivers. It enables simplified control of complex LED matrices by handling clock generation and data synchronization internally. The series is designed to protect data integrity and provide fault reporting for robust display applications.

Specialized Replacement Considerations

Consult the Texas Instruments product selection guide for direct equivalents within the TLC698x family. Verify pin-to-pin compatibility and electrical parameter overlaps before substituting. No public substitute part numbers are confirmed for this specific model.
