MAX4508/MAX4509
Fault-Protected, High-Voltage Single 8-to-1/
Dual 4-to-1 Multiplexers with Output Clamps
Detailed Description
Traditional fault-protected multiplexers are constructed
with three series FET switches. This produces good off
protection, but limits the switches input voltage range
to as much as 3V below the supply rails, reducing its
usable dynamic range. As the voltage on one side of
the switch approaches within about 3V of either supply
rail (a fault condition), the switch impedance increases,
limiting the output signal range to approximately 3V
less than the appropriate polarity supply voltage.
The MAX4508/MAX4509 differ considerably from tradi-
tional fault-protected multiplexers, offering several
advantages. First, they are constructed with two paral-
lel FETs, allowing very low resistance when the switch
is on. Second, they allow signals on the NO_ pins that
are within or beyond the supply rails to be passed
through the switch to the COM terminal. This allows rail-
to-rail signal operation. Third, when a signal VNO_
exceeds the supply rails (i.e., a fault condition), the
voltage on COM_ is limited to the supply rails.
Operation is identical for both fault polarities.
