The MAX4598 can be configured as a single 8-channel
or dual 4-channel multiplexer. In the single 8-to-1 multi-
plexer configuration, COMA connects to one of the
eight inputs (NO1 to NO8), GND, or V+ by the address
inputs A0 to A2 (see Truth Table ). In the dual 4-to-1
multiplexer configuration, COMA connects to one of the
four inputs (NO1, NO3, NO5, NO7), GND, or V+, and
COMB connects to one of the four inputs (NO2, NO4,
NO6, NO8) or GND by the address inputs A0 to A2
(see Truth Table ).
The MAX4598 functions as a standard multiplexer
when NLATCH is high. When NLATCH is low, the con-
dition set by A0 to A3 is activated at the rising edge of
LATCH. Otherwise, the outputs remain at the previously
set condition.
The MAX4598 construction is typical of most CMOS
analog switches. It has three supply pins: V+, V-, and
GND. The positive and negative power supplies are
used to drive the internal CMOS switches and set the
limits of the analog voltage on any switch. Reverse
ESD-protection diodes are internally connected be-
tween each analog signal pin and V+ and V-. If the volt-
age on any pin exceeds V+ or V- by 0.3V, one of the
ESD diodes starts to conduct. During normal operation
these reverse-biased ESD diodes leak, forming the only
current drawn from V-.
