When several serial devices are configured as slaves,
addressable by the processor, DIN pins of each
decode logic individually control CS of each slave
device. When a slave is selected, its CS pin is driven
low, data is shifted in, and CS is driven high to latch the
data. Typically, only one slave is addressed at a time.
DOUT is not used.
The MAX395 can be used as a multiplexer, but to
obtain the same electrical performance with slightly
improved programming speed, use the MAX349 8-
channel mux or the MAX350 dual 4-channel mux, both
in 18-pin packages.
