DESCRIPTION

Serial data input for driver on/off control; Schmitt buffer input. When SIN is high, data

'1' are

SIN

2

I

written into the LSB of the 16-bit shift register at the SCLK rising edge.

Serial data shift clock; Schmitt buffer input. All data in the 16-bit shift register are shifted toward

SCLK

I

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

LAT

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 k

Ω (typ)

resistor.

Blank, all outputs; Schmitt buffer input. When BLANK is high, all constant-current outputs

(OUT0

–OUT15) are forced off. When BLANK is low, all constant-current outputs are controlled by

BLANK

resistor.

Constant-current value setting, OUT0

–OUT15 sink constant-current is set to desired value by

connection to an external resistor between IREF and GND.

Serial data output. This output is connected to the MSB of the 16-bit shift register. SOUT data
