DESCRIPTION
2
Blank (Light OFF). When BLANK=H, All OUTx outputs are forced OFF. When BLANK=L,
ON/OFF of OUTx outputs are controlled by input data.
Ground
I/O
Reference current terminal
I
Mode select. When MODE=L, SIN, SOUT, SCLK, XLAT are connected to ON/OFF control
logic. When MODE=H, SIN, SOUT, SCLK, XLAT are connected to dot-correction logic.
O
Constant current output
