PARALLEL INTERFACE
The parallel interface of the AD7819 is eight bits wide. The
output data buffers are activated when both
CS
and
RD
are
logic low. At this point the contents of the data register are
placed on the 8-bit data bus. Figure 15 shows the timing diagram
for the parallel port. The Parallel Interface of the AD7819 is reset

when BUSY goes logic high. Care must be taken to ensure that
a read operation does not occur while BUSY is high. Data
read from the AD7819 while BUSY is high will be invalid. For
optimum performance the read operation should end at least
100 ns (t

) prior to the falling edge of the next
