Overview
The DG418BDY-E3 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a ±15 V analog signal range and features a maximum on-resistance of 25 Ω at room temperature, extending to 29 Ω across the full -40 °C to +85 °C operating range. The device supports dual supplies from ±5 V to ±20 V or single supplies up to 36 V. Key dynamic characteristics include a turn-on time of 89 ns and a turn-off time of 80 ns under standard test conditions. Supply currents are minimal, typically 1 µA maximum. The component is housed in an 8-pin narrow SOIC package.
Feature Summary
- Monolithic quad SPST configuration utilizing high voltage silicon gate process
- TTL and CMOS compatible logic control with inverted input sense
- Low power consumption suitable for battery-powered applications
- Epitaxial layer design prevents latchup
Applications
- Precision test equipment
- Battery powered systems
- Sample-and-hold circuits
- Military radios
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as indicated by the E3 suffix. Ensure the supply chain source provides valid traceability for the Vishay Siliconix manufacturing origin.
Selection Notes
Select this component when a quad SPST topology with low on-resistance is required. Verify that the logic input polarity matches the system design, as the DG418B responds to opposite control levels compared to the DG417B. Ensure the analog signal range does not exceed the specified ±15 V limits.
Part Context
This part belongs to the DG417B/DG418B/DG419B family of precision analog switches. While sharing the same core technology and package options, the DG418B is distinguished by its specific logic truth table relative to the DG417B. The DG419B variant offers SPDT functionality with break-before-make switching.

FAQ
How does the logic control of the DG418B differ from the DG417B?
The DG418B responds to opposite control logic levels compared to the DG417B. A Logic '0' turns the DG417B ON but keeps the DG418B OFF.
What is the guaranteed behavior for the DG419B variant?
Break-before-make switching is guaranteed for the DG419B, which utilizes an SPDT configuration.
