The TLC59025 is designed for LED displays and LED lighting applications. The TLC59025 contains a 16-bit shift

register and data latches, which convert serial input data into parallel output format. At the TLC59025 output

stage, 16 regulated-current ports provide uniform and constant current for driving LEDs within a wide range of VF

variations. Used in system design for LED display applications (e.g., LED panels), the TLC59025 provides great

flexibility and device performance. Users can adjust the output current from 3 mA to 45 mA through an external

at the output port. The high clock frequency, 30 MHz, also satisfies the system requirements of high-volume data

transmission.

The serial data is transferred into TLC59025 via SDI, shifted in the shift register, and transferred out via SDO. LE

can latch the serial data in the shift register to the output latch. OE enables the output drivers to sink current.
