DG211EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211EUE+ is a normally closed, quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual power supplies ranging from ±4.5V to ±18V and features a TSSOP-16 package. The device guarantees break-before-make switching and non-latching behavior when supplies are disconnected. Electrical specifications include a maximum drain-source on-resistance of 175 Ohms at ±10V, a maximum turn-on time of 1000ns, and a maximum turn-off time of 500ns. Supply current is limited to 400uA maximum, and the component supports continuous operation within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching prevents signal overlap during transitions.
• Non-latching design ensures safe operation even if power supplies are removed while input signals remain connected.
• CMOS construction eliminates the need for a separate logic supply voltage (VL).
• Compatible with both CMOS and TTL logic control inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUE+' corresponds to the TSSOP-16 package and the -40°C to +85°C operating temperature range. Confirm that the ordering information matches the intended application requirements before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed SPST switching with guaranteed break-before-make timing. Ensure the system provides dual power supplies between ±4.5V and ±18V. Consider the 175 Ohm maximum on-resistance and 1000ns turn-on time against signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG201A/DG211 family of quad SPST CMOS analog switches. The DG211 variant is distinguished from the DG201A primarily by slower switching speeds, specifically a longer maximum turn-on time of 1000ns compared to the DG201A's 600ns.

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative components.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the DG211EUE+ require a third logic supply voltage?

No, the Maxim version of the DG211 eliminates the need for the third (VL) power supply required by original manufacturer products.

What happens if the power supplies are turned off while input signals are present?

The device is guaranteed not to latch up if the power supplies are disconnected with input signals still connected.

What is the maximum turn-on time for the DG211?

The maximum turn-on time for the DG211 is 1000ns.
