DG411FEUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411FEUE+T is a monolithic CMOS analog switch IC featuring four independent single-pole single-throw (SPST) channels with normally closed (NC) configuration. It provides fault protection capabilities, including ±36V overvoltage protection during power-up and ±40V fault protection when powered down. The device supports dual supply voltages ranging from ±4.5V to ±20V or single supplies from +9V to +36V. Key electrical parameters include a maximum on-resistance of 35Ω at 25°C, a typical fault response time of 20ns, and a maximum power dissipation of 755mW. It operates within a temperature range of -40°C to +85°C and is housed in a TSSOP-16 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus tube variants. Confirm RoHS compliance status through official manufacturer documentation. Ensure the NC logic polarity matches system requirements compared to NO alternatives.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed signal paths with high-voltage fault tolerance. Compare on-resistance and leakage specifications against DG411EUE+ if fault protection is unnecessary. Verify voltage ratings align with peak signal amplitudes.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411F family of fault-protected analog switches. It serves as an enhanced version of the standard DG411, adding robust protection features while maintaining pin compatibility. The series addresses reliability needs in harsh industrial and aerospace environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411EUE+T lacks fault protection features. DG412FEUE+T offers normally open (NO) configuration instead of normally closed. DG413FEUE+T provides mixed NC/NO channel configurations.
