Separate on-chip latches are provided for each of the four DACs. Data is transferred into one of these data latches through a mon 8-bit TTL /CMOS-patible 5-V input port. Control inputs A0 and A1 determine which DAC is loaded when WR goes low. The control logic is speed patible with most 8-bit microprocessors.
