DG417BDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417BDQ-T1-E3 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates with dual supplies of ±15 V or a single supply up to 12 V, providing an analog signal range of ±15 V. The device features a maximum on-resistance of 25 Ω and low leakage currents. Key dynamic characteristics include a turn-on time of 89 ns and a turn-off time of 80 ns at room temperature under full specifications. It is housed in an 8-pin MSOP package and supports TTL and CMOS logic levels.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against the official Vishay datasheet (Document Number: 72107) to confirm pinout alignment and electrical tolerances. Ensure the MSOP-8 footprint matches the JEDEC MO-187 variation AA and BA dimensions provided in the package drawing. Validate RoHS compliance status as indicated by the -E3 suffix.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage handling and low distortion are required in a compact surface-mount form factor. The DG417B series offers a balance of speed and on-resistance suitable for precision instrumentation. Consider the specific logic level requirements, as the DG417B responds to opposite control logic compared to the DG418B variant within the same family.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG417B/DG418B/DG419B family of precision monolithic quad SPST analog switches. Manufactured using Vishay's high voltage silicon gate process, these devices are designed for efficient board space usage in industrial and military applications. The DG417B specifically provides single-pole single-throw switching functionality.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG417BDJ-E3 serves as a through-hole alternative in an 8-pin MiniDIP package. For surface-mount needs, the DG417BDY-E3 offers the same electrical characteristics in an SOIC-8 package. Verify that the replacement package maintains compatibility with the existing PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range supported by the DG417BDQ-T1-E3?

The device supports an analog signal range of ±15 V when operated with dual supplies, or 0 V to 12 V with a single supply.

How does the DG417B differ from the DG418B in terms of control logic?

The DG417B and DG418B respond to opposite control logic levels; a Logic '0' turns the DG417B on while it turns the DG418B off.

Is break-before-make switching guaranteed for the DG417B?

No, break-before-make switching is guaranteed only for the DG419B variant, which has an SPDT configuration. The DG417B is an SPST switch.
