DI

I

Serial data input pin. This pin inputs serial data with a data length of 12

bits. (Do not leave the pin floating.)

11

DO

O

This pin outputs the MSB data in the 12-bit shift register at the CLK falling

edge.

13

CLK

I

Shift clock input pin. The input signal from the DI pin enters the 12-bit shift

register at the rising edge of the shift clock pulse. (Do not leave this pin

floating.)

LD

I

When the LD pin inputs the High-level signal, shift register value is loaded

to the decoder and the D/A output register. (Do not leave this pin floating.

When data is not transferred, fix the pin to the “Low” level.)
