TLC59281 - 16-Channel Constant-Current LED Driver

General Description

The TLC59281 is a 16-channel, constant-current sink LED driver.

Each channel can be turned on/off by writing serial data to an internal register.

The constant-current value of all 16 channels is set by a single external resistor.
