interface logic information
Address lines A0 and A1 select which DAC accepts data from the input port. Table 2 shows the operations of
the four DACs. Figure 6 shows the input control logic. When the WR signal is low, the input latches of the
selected DAC are transparent and the output responds to activity on the data bus. The 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.
