DG418LEDQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG418LEDQ-T1-GE3 is a single-pole single-throw (SPST) analog switch from the Vishay Siliconix DG418LE series, housed in an 8-lead MSOP package. It operates on a single supply of +3 V to +16 V or dual supplies of ±3 V to ±8 V. The device features a typical drain-source on-resistance of 6 Ω at room temperature and maximum limits up to 10 Ω across the full operating range. Switching speeds include a maximum turn-on time of 38 ns and turn-off time of 32 ns under standard test conditions. It supports CMOS/TTL logic inputs and maintains low power dissipation with supply currents typically below 1 μA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Advanced LC2MOS CMOS technology ensures low power dissipation while maintaining fast switching speeds and low on-resistance.
• Break-before-make switching action prevents signal overlap during transitions.
• CMOS and TTL compatible control logic allows direct interfacing with standard digital systems.
• Analog signal range extends from V- to V+, supporting rail-to-rail signal handling.

• Data acquisition systems
• Medical instruments
• Precision instrumentation
• Automated test equipment
• Sample and hold circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm RoHS compliance status and package variant. Confirm that the MSOP-8 package dimensions match the design footprint requirements. Check for any recent product change notices regarding manufacturing location or material composition updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low-voltage SPST switch with minimal on-resistance is required. Ensure the application voltage stays within the +3 V to +16 V single supply or ±3 V to ±8 V dual supply limits. Consider the 6 Ω on-resistance impact on signal integrity for high-current paths. Verify that the 38 ns switching speed meets the system timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG417LE/DG418LE/DG419LE family, which serves as lower-voltage, pin-for-pin compatible replacements for the industry-standard DG417/DG418/DG419 series. The DG418LE specifically provides a normally-open configuration, distinguishing it from the DG417LE (normally-closed) and DG419LE (SPDT).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG418LEDY-T1-GE4 offers the same electrical specifications in an SOIC-8 package instead of MSOP-8. DG418LDY-T1-GE4 is a higher-voltage variant requiring different supply ranges. Verify pin compatibility and thermal performance when substituting packages.
