DESCRIPTION
O Constant sink current driver outputs.
O Multiple outputs can be configured in parallel to increase the sink drive current capability.
O Different voltages can be applied to each output.
— Power ground
O Serial data output
I Serial data input. This pin is internally pulled down to GND with a 1-MΩ (typ) resistor.
I/O
Output current programming pin. A resistor connected between IREF and GND sets the current for
each constant-current output. Place the external resistor close to the device.
— Power-supply voltage

(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 my affect device reliability.
(2) All voltages are with respect to network ground pin.
