Dual, Differential 4-Channel Multiplexer
The MAX350 can be programmed normally, with only
one differential channel selected for every eight clock
pulses, or it can be programmed in a fast mode, where
channel changing occurs on each clock pulse.
In fast mode, select the channels by sending two high
pulses, spaced four clock pulses apart (corresponding
to the two selected channels) at DIN, and a corre-
sponding CS low pulse for each of the first eight clock
pulses. As SCLK clocks this through the register, each
switch sequences one differential channel at a time,
starting with channel 0. Repeat this process for subse-
quent channel sequencing after the first eight bits have
been sent. For even faster channel sequencing, send
only one DIN high pulse and one CS low pulse for
every four clock pulses.
Reset Function
RESET is the internal reset pin. It is usually connected
to a logic signal or V+. Drive RESET low to open all
switches and set the contents of the internal shift regis-
ter to zero simultaneously. When RESET is high, the
part functions normally and DOUT is sourced from V+.
RESET must not be driven beyond V+ or GND.
