BLOCK DIAGRA
PIN
SDO (Pin 10): Serial Interface Data Output. The serial
output of the shift register appears at the SDO pin. The data
transferred to the device via the SDI pin is delayed 32 SCK
rising edges before being output at the next falling edge.
This pin is used for daisy-chain operation.

CLR (Pin 11): Asynchronous Clear Input. A logic low at this
level-triggered input clears all registers and causes the
DAC voltage outputs to drop to 0V. CMOS and TTL-
compatible.
