Pin status is controlled by input data.
See “

Shift clock signal input pin.
When CS = “L,” SI data is loaded into the shift register at the rising edge of the
shift clock.
20
SI*
2
Data input pin (serial input pin).
Used for 16-bit serial data input.
21
SO
Data output pin (serial output pin).
The first bit (LSB) data of the 16-bit shift register is output simultaneously with
the falling edge of the shift clock.
When CS output = “H,” this pin goes to high impedance state.
22
CS*
2
Chip select signal input pin.
Input to shift registers is enabled when the CS signal falling edges. Shift register
contents can be executed when the CS signal rising edges.

1
Analog unit power supply pin (OP amplifier power supply).
24
GND
Common GND pin.
