TERMINAL FUNCTIONS
I/O
DESCRIPTION
I
Serial data input for driver on/off control; Schmitt buffer input. When SIN is high, data '1' are
written into the LSB of the 16-bit shift register at the SCLK rising edge.
I
Serial data shift clock; Schmitt buffer input. All data in the 16-bit shift register are shifted toward
the MSB by 1-bit synchronization of SCLK.
Level triggered latch; Schmitt buffer input. The data in the 16-bit shift register continue to transfer
to the output on/off data latch while LAT is high. Therefore, if the data in the 16-bit shift register
I are changed when LAT is high, the data in the data latch are also changed. The data in the data
latch are held when LAT is low. This pin is internally pulled down to GND with a 500 kΩ (typ)
resistor.
Blank, all outputs; Schmitt buffer input. When BLANK is high, all constant-current outputs
I
(OUT0–OUT15) are forced off. When BLANK is low, all constant-current outputs are controlled by
the data in the output on/off data latch. This pin is internally pulled up to VCC with a 500 kΩ (typ)
resistor.
I/O
Constant-current value setting, OUT0–OUT15 sink constant-current is set to desired value by
connection to an external resistor between IREF and GND.
O
Serial data output. This output is connected to the MSB of the 16-bit shift register. SOUT data
changes at the rising edge of SCLK.
O
Constant-current output. Each output can be tied together with others to increase the
constant-current. Different voltages can be applied to each output.
