DG417DY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417DY-T1 is a precision CMOS analog switch manufactured by Vishay Siliconix, housed in an 8-lead narrow SOIC surface-mount package. It features a single SPST configuration with normally closed contacts. The device supports dual supply voltages ranging from ±5 V to ±20 V and operates within a temperature range of -40 °C to +85 °C. Key electrical specifications include a maximum on-resistance of 35 Ω, a turn-on time of 175 ns, and a turn-off time of 145 ns. The component draws a maximum power supply current of 1 μA and dissipates up to 400 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Confirm that the manufacturer designation matches Vishay / Siliconix or Vishay Semiconductors. Ensure the part number corresponds to the narrow SOIC variant rather than the MiniDIP version. Cross-reference RoHS compliance details if required for the specific manufacturing lot.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed single-channel analog switch is required. Verify that the 35 Ω maximum on-resistance meets the circuit's signal integrity requirements. Ensure the operating environment falls within the specified -40 °C to +85 °C temperature range. Confirm that the 44 V absolute maximum supply rating accommodates the system's voltage peaks.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG417/DG418/DG419 series of monolithic CMOS analog switches. The DG417 specifically provides a normally closed (NC) single-pole single-throw (SPST) configuration. It is designed alongside the DG418 (normally open) and DG419 (single-pole double-throw) variants within the same datasheet document.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic state required to close the DG417 switch?

A Logic '0' input (≤ 0.8 V) turns the switch ON (closes the circuit), while a Logic '1' input (≥ 2.4 V) turns it OFF.

Does the DG417 support break-before-make switching?

No, break-before-make switching is guaranteed only for the DG419 variant. The DG417 and DG418 do not have this feature.

What is the maximum analog signal range supported by the DG417?

The analog signal range is ±15 V when using dual supplies of ±15 V.
