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.
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.
Applications
- Data acquisition systems
- Medical instruments
- Precision instrumentation
- Automated test equipment
- Sample and hold circuits
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.
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.
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).
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.
