INT E RFACE LOGIC INFORMAT ION
Address lines A0 and A1 select which DAC will accept data
from the input port. T able I shows the selection table for the
four DACs with Figure 4 showing the input control logic. When
the
WR
signal is LOW, the input latches of the selected DAC
are transparent and its output responds to activity on the data
bus. T he data is latched into the addressed DAC latch on the
rising edge of
WR
. While
WR
is high the analog outputs remain
at the value corresponding to the data held in their respective
latches.
