A standard
μ
-processor and TTL/CMOS compatible input
data port loads the data into the pre-selected DACS. If CS = 0,
thechipaccesses digitaldataonthe bus. Thenaddress bitsA0
toA2selecttheappropriateDACandLD1loadsthedataintothe
first-latch-bank.
When all 8-channels first-latch-banks are
loaded, then LD2 enables the second-latch-bank and updates
all 8-channels simultaneously. The selected DAC becomes
transparent (activity on the digital inputs appear at the analog
output) when both LD1 = LD2 = 0.
R1 = 0 resets the first-latch-bank. R2 = 0 resets the second-
latch-bank which sets the analog output to zero volts (data =
100...00), regardless of digital inputs.
