MICROPROCESSOR INTERFACING
The DAC8426 easily interfaces to most 8- and 16-bit wide data-
bus systems. Serial and 4-bit busses can also be accommodated
with additional latches and control circuitry. Interfacing can be
accomplished with databus transfers running with 50 ns write
pulse widths.
Examples of various microprocessor interface circuits are pro-
vided in Figures 8 through 12. These figures have omitted cir-
cuitry not essential to the bus interface. The design process
should include review of the DAC8426 timing diagram with the
