Overview
The DG412FEUE+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features fault protection for inputs and rail-to-rail signal handling capability. The device operates with dual power supplies ranging from ±4.5V to ±20V or a single supply between +9V and +36V. On-resistance is typically 25Ω with a maximum of 45Ω at +25°C. Turn-on time is up to 220ns and turn-off time is up to 160ns under dual supply conditions. The component is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Fault-protected inputs and rail-to-rail signal handling capability
- Pin compatible with industry-standard non-protected DG411/DG412/DG413
- All switches turn off when power is removed
Applications
- Communication Systems
- Signal Routing
- Test Equipment
- Data Acquisition
- Industrial and Process Control Systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm RoHS compliance status and package type. Ensure that any substitutions maintain identical pin configurations and electrical characteristics to guarantee direct replacement compatibility within existing circuit designs.
Selection Notes
Select this component for applications requiring high-voltage fault tolerance on analog signal paths. Verify that the required supply voltage falls within the specified single or dual supply ranges. Confirm that the logic input thresholds align with the system's control voltage levels for reliable switching operation.
Part Context
This part belongs to the DG411F/DG412F/DG413F family of quad SPST analog switches. The DG412F variant specifically provides four normally open switches. These devices are designed as direct replacements for legacy non-fault-protected CMOS switches while offering enhanced overvoltage protection capabilities.

FAQ
What is the maximum fault voltage tolerance with power off?
The DG412FEUE+ can withstand fault voltages up to ±40V on the NO_, NC_, or COM_ terminals when the power is off.
How does the device behave during a fault condition?
During a fault condition, the affected terminal becomes a high impedance open circuit, allowing only microamperes of leakage current to flow regardless of the switch state.
Is no power-supply sequencing required for operation?
Yes, the datasheet specifies that no power-supply sequencing is required for the proper operation of these switches.
