Fault-Protected, Low-Voltage,
Quad SPST Analog Switches
Features
The MAX4711/MAX4712/MAX4713 are fault-protected,
Rail-to-Rail®, low-voltage analog switches featuring low
on-resistance and guaranteed on-resistance flatness over
the specified signal range. Due to the fault protection feature the analog switch input (NO_ or NC_) and output
(COM_) pins are not symmetrical. The fault protection feature allows for the analog input to go beyond the plus or
minus supplies without the device drawing excessive
amounts of current from the analog inputs. When the analog inputs are driven beyond the supply rails when the
switch is on, it will sense a fault and turn itself off and the
analog switch output will be clamped to the same polarity
supply as the input signal and will not go beyond the supply rails. This feature protects any electronic circuitry connected to the output from excessive voltages present on
the analog inputs.
♦ Fault-Protected Analog Inputs
The MAX4711/MAX4712/MAX4713 are quad, singlepole/single-throw (SPST) analog switches. The MAX4711
has four normally closed switches (NC), the MAX4712 has
four normally open switches (NO), and the MAX4713 has
two NO and two NC switches. Switching times are less
than 125ns for tON, and less than 80ns for tOFF. These
switches operate from a single +2.7V to +11V supply or
from dual ±2.7V to ±5.5V supplies. All digital inputs have
+0.8V to +2.4V logic thresholds, ensuring both TTL and
CMOS logic compatibility when using ±4.5V to ±5.5V or
single +4.5V to +11V supplies.

Note 1: COM_ pin is not fault-protected. Signals on COM_ exceeding V+ or V- are clamped by internal diodes. Limit forward diode
current to maximum current rating.
Note 2: NO_ and NC_ pins are fault-protected. Signals on NO_ or NC_ exceeding -12V to +12V may damage device. These limits
apply with V+ = V- = 0.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX4711/MAX4712/MAX4713 differ considerably
from traditional fault-protection switches, with several
advantages. First, they are constructed with two parallel FET’s allowing very low on-resistance. Second, they
allow signals on the NC_ or NO_ pins that are within or
slightly beyond the supply rails to be passed through
the switch to the COM terminal, allowing rail-to-rail signal operation. Third, when a signal on NC_ or NO_
exceeds the supply rails by about 150mV (a fault condition) the voltage on COM_ is limited to the same
polarity supply voltage. Operation is identical for both
fault polarities.
During a fault condition, the NO_ or NC_ input
becomes high impedance regardless of the switch
state or load resistance. If the switch is on, the COM_
output current is supplied from V+ or V- by the clamp
FET’s that are connected from COM to each supply.
These FET’s can typically source or sink up to 15mA.
When power is removed, the fault protection is still in
effect. In this case, the NO_ or NC_ terminals are a virtual open circuit. The fault can be up to ±12V.
The COM_ pins are not fault-protected, they act as normal CMOS switch terminals. If a voltage source is connected to any COM_ pin, it should be limited to the
supply voltages. Exceeding the supply voltage will

Negative Supply Voltage Input. Connect to GND for single-supply
operation.
Positive Supply Input
cause high currents to flow through the ESD-protected
diodes, possibly damaging the device (see Absolute
Maximum Ratings).
Pin Compatibility
These switches have identical pinouts to common nonfault-protected CMOS switches. Care should be exercised while considering them for direct replacements in
existing printed circuit boards since only the NO_ and
NC_ pins of each switch are fault-protected.
Internal Construction
Internal construction is shown in Figure 1, with the analog signal paths shown in bold. A single NO switch is
shown; the NC configuration is identical except the
logic-level translator is inverting. The analog switch is
formed by the parallel combination of N-channel FET
(N1) and P-channel FET (P1), which are driven on and
off simultaneously according to the input fault condition
and the logic-level state.
Normal Operation
Two comparators continuously compare the voltage on
the NO_ (or NC_) pin with V+ and V-. When the signal
on NO_ or NC_ is between V+ and V- the switch acts
normally, with FETs N1 and P1 turning on and off in
response to IN_ signals. The parallel combination of
N1 and P1 forms a low-value resistor between NO_ (or

NC_) and COM_ so that signals pass equally well in
either direction.
Positive Fault Condition
When the signal on NO_ (or NC_) exceeds V+ by about
150mV, the high-fault comparator output is high, turning off FETs N1 and P1. This makes the NO_ (or NC_)
input high impedance regardless of the switch state. If
the switch state is “off”, all FETs are turned off and both
NO_ (or NC_) and COM_ are high impedance. If the
switch state is “on”, clamp FET P2 is turned on, sourcing current from V+ to COM_.
Negative Fault Condition
When the signal on NO_ (or NC_) exceeds V- by about
150mV, the low-fault comparator output is high, turning
off FETs N1 and P1. This makes the NO_ (or NC_) input
high impedance regardless of the switch state. If the
switch state is “off”, all FETs are turned off and both
NO_ (or NC_) and COM_ are high impedance. If the
switch state is “on”, clamp FET N2 is turned on, sinking
current from COM_ to V-.
Transient Fault Response and Recovery
When a fast rise-time or fall-time transient on NC_ or
NO_ exceeds V+ or V-, the output (COM_) follows the
input to the supply rail with only a few nanoseconds
delay. This delay is due to the switch on-resistance and
circuit capacitance to ground. When the input transient
returns to within the supply rails, however, there is a
700ns output recovery delay time. These values
depend on the COM_ output resistance and capacitance, and are not production tested or guaranteed.
The delays are not dependent on the fault amplitude.
Higher COM_ output resistance and capacitance
increase recovery times.
COM_ and IN_ Pins
FETs N2 and P2 can source about ±15mA from V+ or
V- to COM_ in the fault condition. Ensure that if the
COM_ pin is connected to a low-resistance load, the
absolute maximum current rating of 40mA is never
exceeded both in normal and fault conditions.

Fault-Protected, Low-Voltage,
Quad SPST Analog Switches
The COM_ pins do not have fault protection. Reverse
ESD-protection diodes are internally connected
between COM_, and V+ and V-. If a signal on COM_
exceeds V+ or V- by more than a diode drop, one of
these diodes will conduct. The IN_ pin can exceed the
positive supply voltage, but they can go below the negative supply by only a diode drop. The maximum voltage on these pins is 12V if operating from a single
supply, regardless of the supply voltage (including 0
volts), and if operating from dual supplies, the maximum voltage is (V- + 12V).
Fault-Protection Voltage and Power Off
The maximum fault voltage on the NC_ or NO_ pins is
±12V with power off.
