(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

The TLC5923 is a 16 channel constant-current sink driver. Each channel has a On/Off state and a 128-step adjustable constant current sink (dot correction). The dot correction adjusts the brightness vari ations between LED,LED channels and other LED drivers.Both dot correction and On/Off state are accessible via a serial data interface. A single external resistor sets the maximum current of all 16 channels.

The TLC5923 features two error information circuits.The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal.The thermal error flag (TEF) indicates an overtemperature condition.
