Typical Operating Characteristics (continued)

The MAX4511/MAX4512/MAX4513 are fault-protected
CMOS analog switches with unusual operation and
construction. Traditional fault-protected switches are
constructed by three series FETs. This produces good
off characteristics, but fairly high on-resistance when
the signals are within about 3V of each supply rail. As
the voltage on one side of the switch approaches with-
in about 3V of either supply rail (a fault condition), the
switch impedance becomes higher, limiting the output
signal range (on the protected side of the switch) to
approximately 3V less than the appropriate polarity
supply voltage.
During a fault condition, the output current that flows
from the protected side of the switch into its load
comes from the fault source on the other side of the
switch. If the switch is open or the load is extremely
high impedance, the input current will be very low. If
the switch is on and the load is low impedance,
enough current will flow from the source to maintain the
load voltage at 3V less than the supply.
