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 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: Electrical specifications at -40°C are not production tested and guaranteed by design.
Note 4: ∆RON = ∆RON(MAX) - ∆RON(MIN).
Note 5: Leakage parameters are 100% tested at maximum rated temperature and with dual supplies and guaranteed by design at +25°C.
Note 6: Guaranteed by design.
Note 7: Off-Isolation = 20 log10 [VCOM/(VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.
Note 8: Between any two switches.
