Overview
The DG417DY-T1-E3 is a precision CMOS analog switch manufactured by Vishay Siliconix, housed in an 8-lead narrow SOIC package. It features a single SPST normally-closed configuration with a maximum on-resistance of 35 Ω and a turn-on time of 175 ns. The device supports dual supply voltages up to ±20 V or a single supply up to 40 V, operating within a temperature range of -40 °C to +85 °C. Key electrical characteristics include ultra-low power dissipation of 35 nW, low leakage currents, and TTL/CMOS compatibility.
Feature Summary
- High-voltage silicon gate process ensures superior switching performance and latchup prevention.
- Ultra-low power consumption suitable for battery-powered applications.
- TTL and CMOS logic compatible for simple interfacing.
Applications
- Precision test equipment
- Battery powered systems
- Sample-and-hold circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm that the narrow SOIC-8 variant matches the required footprint and pinout for the target design. Ensure the component meets the necessary environmental specifications for the intended operating conditions.
Selection Notes
Select this part for designs requiring low on-resistance and high-speed switching in a compact surface-mount package. Consider the DG418 if a normally-open configuration is needed instead of the DG417's normally-closed setup. Verify that the supply voltage requirements align with the specified single or dual supply limits.
Part Context
This component belongs to the DG41x series of precision analog switches from Vishay Siliconix. The series includes variants like the DG418 (normally open) and DG419 (SPDT). These devices are designed for portable and industrial applications where board space efficiency and high signal integrity are critical.

FAQ
What is the logic sense of the DG417?
The DG417 is a normally-closed switch; it turns ON when the logic input is LOW (≤ 0.8 V) and turns OFF when the logic input is HIGH (≥ 2.4 V).
Does the DG417 support break-before-make switching?
No, break-before-make switching is guaranteed only for the DG419 (SPDT) variant. The DG417 and DG418 do not have this feature.
What is the maximum supply voltage rating?
The absolute maximum rating for the positive supply (V+) is 44 V relative to GND.
