Load DAC Input (active low). Driving this asynchronous input low (level sensitive)
transfers the contents of each input latch to its respective DAC latch.
Serial Data Output. Can sink and source current. Data at DOUT is adjustable to be
clocked out on rising or falling edge of SCLK.
Clear DAC input (active low). Driving CLR low causes an asynchronous clear of input
and DAC registers and sets all DAC outputs to zero.
Serial Data Input. TTL/CMOS-compatible input. Data is clocked into DIN on the
rising edge of SCLK. CS must be low for data to be clocked in.
Serial Clock Input. Data is clocked in on the rising edge and clocked out on either the
rising (default) or the falling edge.
Chip-Select Input (active low). Data is shifted in and out when CS is low. Programming
commands are executed when CS rises.
