Overview
The DG417LEDQ-T1-GE3 is a single-channel SPST analog switch from the Vishay Siliconix DG417LE 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 on-resistance of 6 Ω and supports bidirectional signal conduction with break-before-make switching action. Key electrical parameters include a maximum turn-on time of 38 ns and a maximum turn-off time of 32 ns at room temperature under standard test conditions. The component is designed for low power dissipation and CMOS/TTL compatibility.
Feature Summary
- Advanced CMOS technology provides low on-resistance and fast switching speeds with minimal power dissipation.
- Bidirectional signal conduction allows equal performance in both directions when the switch is on.
- Break-before-make switching action prevents signal overlap during transitions.
- Control logic input tolerance exceeds the positive supply voltage (V+).
Applications
- Data acquisition systems
- Medical instruments
- Precision instruments
- Communications systems
- Automated test equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and RoHS compliance status. Confirm that the MSOP-8 variant matches the required footprint for the design. Cross-reference the part number with official Vishay databases to validate availability and check for any recent revisions to the datasheet specifications.
Selection Notes
Select this component for applications requiring low-voltage operation between +3 V and +16 V. Ensure the circuit design accommodates the specified on-resistance variation across temperature ranges. Verify that the control logic levels are compatible with the CMOS/TTL interface requirements. Consider the thermal derating characteristics if operating near the maximum power dissipation limits.
Part Context
This part belongs to the DG417LE family, which serves as lower voltage pin-for-pin compatible replacements for the industry-standard DG417 devices. The 'DQ' suffix indicates the 8-lead MSOP package configuration, while 'GE3' denotes Green (RoHS compliant) packaging. It is functionally distinct from the DG418LE (normally open) and DG419LE (SPDT) variants within the same series.
Replacement Considerations
The DG417LDQ-T1-E3 is listed as a direct replacement option for the DG417LDQ-T1. Designers should verify that the legacy part's specifications align with the DG417LE series requirements before substitution.
