DG417DY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417DY-E3 is a precision single-pole single-throw (SPST) normally closed analog switch manufactured by Vishay Siliconix. It operates within a ±15 V analog signal range and supports dual or single supply voltages up to 44 V maximum. The device features a typical on-resistance of 20 Ω, with a maximum of 35 Ω across the -40 °C to +85 °C temperature range. Key dynamic characteristics include a turn-on time of 100 ns and a turn-off time of 60 ns. Power consumption is ultra-low at 35 nW, with leakage currents typically below 0.25 nA. It utilizes an epitaxial layer for latchup prevention and is housed in an 8-pin narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'E3' confirms RoHS compliance and lead-free terminations. Confirm the 'DY' designation matches the required 8-pin narrow SOIC surface-mount package. Ensure the operating environment stays within the specified -40 °C to +85 °C range to maintain guaranteed electrical parameters.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring normally closed SPST switching with low on-resistance. Consider the DG418 if normally open logic is preferred, or the DG419 for single-pole double-throw configurations. Verify that the 20 Ω typical on-resistance meets the signal integrity requirements of the specific application circuit.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the DG417 switch?

The DG417 is a normally closed (NC) switch, meaning the channel conducts when the logic input is low.

How does the DG417 handle signals exceeding the supply rails?

Signals on the source or drain pins exceeding V+ or V- will be clamped by internal diodes. Forward diode current must be limited to maximum ratings.

Is the DG417 latchup-proof?

Yes, an epitaxial layer is included in the high voltage silicon gate process to prevent latchup.
