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.

DG411F/DG412F/DG413F Quad, Rail-to-Rail, Fault-Protected, SPST Analog Switches the switch state. If the switch state is off, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. 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.
