Output Enable input. Active low. When O ¯ ¯ E ¯ = High, all OUTx outputs are forced OFF. When O ¯ ¯ E ¯ = Low,
ON/OFF of OUTx outputs are controlled by input data.
Logic supply ground.
Active Pull-up Enable. When connected to LED Load Supply (V
= disabled.
Reference current input/output terminal.
Logic input, Mode select. When MODE = Low, then SDI, SDO, CLK, LE are connected to ON/OFF control
logic. When MODE = High, SDI, SDO, CLK, LE are connected to dot-correction logic.
No connection. Not internally connected.
Constant current outputs.
Power ground.
Data shift clock input. Note that the internal connections are switched by input at MODE pin. At CLK↑, the
shift-registers selected by MODE shift the data.
Serial Data In. Data input of serial data interface.
Serial Data Out. Data output of serial data interface.
Logic Supply.
Error output. FAULT is open drain terminal. FAULT goes low when LOD or TSD detected.
Latch Enable input. Note that the internal connections are switched by input at the MODE pin. At LE↑, the
latches selected by MODE get new data.
Exposed pad for enhanced thermal dissipation; not connected internally, connect to power ground plane.
