Quad, Rail-to-Rail, Fault-Protected,
SPST Analog Switches
General Description
The DG411F/DG412F/DG413F are quad, single-pole/sin-
gle-throw (SPST), fault-protected analog switches. They
are pin compatible with the industry-standard nonpro-
tected DG411/DG412/DG413. These new switches fea-
ture fault-protected inputs and Rail-to-Rail
signal-
handling capability. All terminals are protected from
overvoltage faults up to ±36V with power on and up to
±40V with power off. During a fault condition, the COM,
NO, or NC terminal becomes an open circuit and only
microamperes of leakage current flow from the source.
On-resistance is 35Ω (max) and is matched between
switches to 1.5Ω (max) at +25°C.
The DG411F has four normally closed (NC) switches.
The DG412F has four normally open (NO) switches.
The DG413F has two NC and two NO switches. These
CMOS switches operate with dual power supplies rang-
ing from ±4.5V to ±20V or a single supply between +9V
and +36V. All digital inputs have +0.8V and +2.4V logic
thresholds, ensuring both TTL and CMOS logic com-
patibility when using ±15V or a single +12V supply.
For supply voltages of ±5V, +5V, and +3V, refer to the
MAX4711/MAX4712/MAX4713 data sheet.

Note 1:
COM_, NO_, and NC_ pins are fault protected. Signals on COM_, NO_, and NC_ exceeding -36V to +36V may damage the
device during power-on conditions. When the power is off, the maximum range is -40V to +40V.
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.
