DG417LDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417LDY+ is a precision, monolithic CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single-pole/single-throw (SPST) configuration housed in an 8-pin SOIC package. The device operates with a single supply voltage ranging from +9V to +36V or dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 35Ω, a turn-on time of 175ns, and a turn-off time of 185ns. It supports rail-to-rail analog signal handling and maintains low off-leakage current across the extended temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• +3V logic-compatible digital inputs ensure compatibility with standard TTL and CMOS logic families.
• Power-supply sequencing-free operation eliminates the need for specific power-up sequences or external latchup prevention diodes.
• Rail-to-rail analog signal handling capability allows the switch to conduct signals equally well in either direction across the full supply range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the complete part number including suffixes such as '+' for RoHS compliance when sourcing. Confirm the package type matches the required footprint, as this model utilizes an 8-pin SOIC housing. Cross-reference the manufacturer's latest datasheet for any updates regarding pin configurations or absolute maximum ratings before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG417LDY+ when a normally closed SPST configuration is required within a compact surface-mount design. Ensure the application operates within the specified single or dual supply voltage limits. Consider the guaranteed on-resistance matching and flatness if signal integrity across varying input levels is critical for the system performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG417L/DG418L/DG419L family of precision analog switches. While the DG417L provides a normally closed SPST function, the DG418L offers a normally open SPST, and the DG419L provides an SPDT configuration. All variants share identical electrical characteristics and package options, differing primarily in their internal switch logic states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed direct substitutes include the DG418LDY+ and DG419LDY+. These parts share the same package and electrical specifications but differ in switch configuration. Verify that the alternative part's logic state aligns with the circuit requirements before substitution.
