DG1411EQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG1411EQ-T1-GE3 is a precision monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features four independently selectable switches with a normally closed configuration. The device operates from a single supply of 4.5 V to 24 V or dual supplies of ±4.5 V to ±16.5 V. Key electrical parameters include a typical on-resistance of 1.5 Ω, maximum turn-on time of 190 ns, and maximum turn-off time of 160 ns at +125 °C. It supports rail-to-rail signal handling and offers low charge injection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against current Vishay documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as manufacturing locations may vary. Ensure the component meets the required temperature range specifications for the intended application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed analog switch topology is required for signal routing. Compare on-resistance matching and leakage current specifications against system requirements. Verify that the TSSOP-16 package dimensions fit the PCB layout constraints. Consider thermal dissipation limits if operating near maximum junction temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG141x family of precision analog switches, which includes the DG1412 (normally open) and DG1413 (mixed NC/NO). All variants share similar electrical characteristics and pinouts but differ in default switch states. The EQ suffix denotes the TSSOP-16 surface-mount package variant within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include DG1412EQ-T1-GE3 and DG1413EQ-T1-GE3, provided the different switch logic states are acceptable. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
