Overview
The DG417DJ-E3 is a precision monolithic CMOS analog switch manufactured by Vishay Siliconix. It features a single-pole single-throw (SPST) configuration with normally closed contacts, housed in an 8-pin plastic MiniDIP package. The device operates on dual supplies ranging from ±5 V to ±20 V or a single supply up to 40 V. Key electrical parameters include a maximum drain-source on-resistance of 35 Ω and a turn-on time of 175 ns. It supports a ±15 V analog signal range, exhibits ultra-low power consumption with a typical dissipation of 35 nW, and maintains TTL and CMOS logic compatibility.
Feature Summary
- Built on high-voltage silicon gate process for superior switching performance
- Provides wide dynamic range with low signal errors and distortion
- Features simple interfacing due to TTL and CMOS logic compatibility
- Designed for efficient board space utilization in portable applications
Applications
- Precision test equipment
- Battery powered systems
- Sample-and-hold circuits
- Military radios
- Guidance and control systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance status and termination finish. Confirm that the component meets RoHS requirements if applicable to the design. Ensure the selected package variant matches the intended PCB footprint and mounting style. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a normally closed SPST configuration is required for analog signal routing. Consider the 35 Ω maximum on-resistance and 175 ns switching speed for timing constraints. Evaluate the ±15 V analog signal range against the application's voltage levels. Verify that the MiniDIP package dimensions fit the available board space and assembly capabilities.
Part Context
The DG417DJ-E3 belongs to the DG417/DG418/DG419 series of precision CMOS analog switches. This family shares common manufacturing processes and core specifications, differing primarily in contact configuration and packaging options. The DG417 specifically provides the normally closed function within this lineup, distinguishing it from the normally open DG418 and the SPDT DG419 variants.

FAQ
What is the logic sense of the DG417?
The DG417 responds to opposite control logic levels compared to the DG418. A Logic '0' turns the switch On, while a Logic '1' turns it Off.
Does the DG417 support break-before-make switching?
No, break-before-make switching is guaranteed only for the DG419 (SPDT) configuration. The DG417 is an SPST switch.
What is the maximum supply voltage rating?
The absolute maximum rating for the positive supply (V+) is 44 V. The recommended operating range for dual supplies is ±5 V to ±20 V.
