Fault-Protected, Low-Voltage,
Quad SPST Analog Switches
General Description
Features
♦ Fault-Protected Analog Inputs
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 fea-
ture the analog switch input (NO_ or NC_) and output
(COM_) pins are not symmetrical. The fault protection fea-
ture 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 ana-
log 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 sup-
ply rails. This feature protects any electronic circuitry con-
nected to the output from excessive voltages present on
the analog inputs.

♦ 1Ω (max) On-Resistance Match Between Channels
♦ Single- and Dual-Supply Operation
The MAX4711/MAX4712/MAX4713 are quad, single-
pole/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

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.
