The TLC59281RGER is a linear LED driver from Texas Instruments that integrates a 16-bit shift register and constant-current sink outputs. Each of the 16 channels delivers up to 35 mA, set by an external resistor, with a maximum output compliance of 17 V. The shift register clock runs at 35 MHz, allowing fast serial data updates for multiplexed or large LED arrays.
Both are 16-channel linear LED drivers with shift register topology, but the TLC5940RHBR supports a higher per-channel current of 120 mA versus 35 mA for the TLC59281RGER. The TLC59281RGER operates at a 35 MHz clock rate; the TLC5940RHBR runs at 30 MHz. Package and pinout differ — the TLC5940RHBR comes in a 32-pin QFN, so a direct drop-in replacement without board layout changes is not possible.
