Terminal Functions
I/O
DESCRIPTION
I
Blank (Light OFF). When BLANK=H, All OUTn outputs are forced OFF. When BLANK=L,
ON/OFF of OUTn 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.

I
Data shift clock. Note that the internal connections are switched by MODE (pin #30). At
SCLK↑, the shift-registers selected by MODE shift the data.
I Data input of serial I/F
O Data output of serial I/F
Power supply voltage
O
Error output. XERR is open drain terminal. XERR transistions from H to L when LOD or TEF
detected.
Data latch signal. When MODE = L (ON/OFF data mode), XLAT is an edge-triggered latch
signal of ON/OFF registers. The serial data in ON/OFF input shift registers is latched into the
I
ON/OFF registers at the rising edge of XLAT. When MODE = H (DC data mode), XLAT is a
level-triggered latch signal of dot correction registers. The serial data in DC input shift
registers is written into dot correction registers when XLAT = H. The data in dot correction
registers is held constant when XLAT = L.
