General Description

The TLC59282 is a 16-channel, constant-current sink driver.

Each channel can be individually controlled via a simple serial communications protocol that is compatible with 3.3 V or 5 V CMOS logic levels, depending on the operating VCC.

Once the serial data buffer is loaded, a rising edge on LATCH transfers the data to the LEDx outputs.
