DG411F/DG412F/
DG413F
General Description
The DG411F/DG412F/DG413F are quad, single-pole/single-throw (SPST), fault-protected analog switches. They
are pin compatible with the industry-standard nonprotected DG411/DG412/DG413. These new switches feature
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 ranging 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 compatibility when
using ±15V or a single +12V supply.

SPST Analog Switches

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.

2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
3: Electrical specifications at -40°C are not production tested and guaranteed by design.
4: ΔRON = ΔRON(MAX) - ΔRON(MIN).
5: Leakage parameters are 100% tested at maximum rated temperature and with dual supplies and guaranteed by design at

Detailed Description
The DG411F/DG412F/DG413F are fault-protected CMOS
analog switches with unique operation and construction.
These switches differ considerably from traditional faultprotection switches, with several advantages. First, they
are constructed with two parallel FETs, allowing very low
on-resistance when the switch is on. Second, they allow
signals on the NO_ or NC_ pins that are within, or slightly
beyond, the supply rails to be passed through the switch
to the COM_ terminal (or vice versa), allowing true rail-torail signal operation. Third, the DG411F/DG412F/DG413F
have the same fault-protection performance on any of the
NO_, NC_, or COM_ switch inputs. Operation is identical
for both fault polarities. The fault protection extends to
±36V from GND with ±15V supplies.
During a fault condition, the particular overvoltage input
(COM_, NO_, NC_) pin becomes high impedance regardless of the switch state or load resistance. When power is
removed, the fault protection is still in effect. In this case,
the COM_, NO_, or NC_ terminals are a virtual open
circuit. The fault can be up to ±40V with power off. The
switches turn off when V+ is not powered, regardless of V-.
Pin Compatibility
These switches have identical pinouts to common nonfault-protected CMOS switches. They allow for carefree
direct replacement in existing printed circuit boards since
the NO_, NC_, and COM_ pins of each switch are fault
protected.

Logic Control Digital Inputs
Negative-Supply Voltage Input. Connect to GND for singlesupply operation. Bypass with a 0.1µF capacitor to GND.
Positive-Supply Voltage Input. Bypass with a 0.1µF capacitor
to GND.
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 logiclevel translator becomes an inverter. 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 COM_, NO_, and NC_ pins with V+ and V-. When the
signal on COM_, 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_) and COM_ exceeds V+
by about 50mV, the high-fault comparator output is high,
turning off FETs N1 and P1. This makes the NO_ (or NC_)
and COM_ pins 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.

DG411F/DG412F/
DG413F
Negative Fault Condition
When the signal on NO_ (or NC_) and COM_ exceeds
V- by about 50mV, the low-fault comparator output is high,
turning off FETs N1 and P1. This makes the NO_ (or NC_)
and COM_ pins 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.
Transient Fault Response and Recovery
When a fast rise-time and fall-time transient on NO_,
NC_, or COM_ exceeds V+ or V-, the output 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 longer output
recovery time delay. For positive faults, the recovery time
is typically 1μs. For negative faults, the recovery time is
typically 0.5μs. These values depend on the output resistance and capacitance, and are not production tested
or guaranteed. The delays are not dependent on the
fault amplitude. Higher load resistance and capacitance
increase recovery times.
Fault-Protection Voltage and Power Off
The maximum fault voltage on the NO_ (or NC_) and
COM_ pins is ±36V with power applied and ±40V with
power off.
Failure Modes
Exceeding the fault-protection voltage limits on NO_,
NC_, or COM_, even for very short periods, can cause
the device to fail. See the Absolute Maximum Ratings.
The failure modes may not be obvious, and failure in one
switch may or may not affect other switches in the same
package.

SPST Analog Switches
Ground
There is no galvanic connection between the analog signal paths and GND. The analog signal paths consist of
an N-channel and P-channel MOSFET with their sources
and drains paralleled and their gates driven out of phase
to V+ and V- by the logic-level translators. However, the
potential of the analog signals must be defined or at least
limited with respect to GND. V+ and GND power the internal logic and logic-level translators and set the input logic
thresholds. The logiclevel translators convert the logic
levels to switched V+ and V- signals to drive the gates of
the analog switches. This drive signal is the only connection between the power supplies and the analog signals.
IN_ Logic-Level Thresholds
The logic-level thresholds are CMOS and TTL compatible
when V+ is +15V. As V+ is raised, the threshold increases
slightly, and when V+ reaches 25V, the level threshold
is about 2.3V, above the TTL output high-level minimum
of 2.4V, but still compatible with CMOS outputs (see the
Typical Operating Characteristics). V- has no effect on the
logic-level thresholds.
Bipolar Supplies
The DG411F/DG412F/DG413F operate with bipolar supplies between ±4.5V and ±20V. The V+ and V- supplies
need not be symmetrical, but their difference cannot
exceed the absolute maximum rating of 44V.
Single Supply
The DG411F/DG412F/DG413F operate from a single
supply between +9V and +36V when V- is connected to
GND.
