Function
14
DI*
I Data input pin
Serial data input pin.
This pin inputs 12-bit length serial data.
11
DO
O Data output pin
This pin outputs MSB bit data of 12-bit shift register.
Shift clock input pin.
13
CLK*
I Shift clock input pin The input signal from the DI pin is inputted to a 12-bit
shift register on the rising edge of the shift clock.
12
LD*
I
Load signal input pin
If input “H” level to LD pin, the data of shift register is
loaded to the decoder and the register for D/A output.
