DG417CY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417CY is a monolithic CMOS single-pole/single-throw (SPST) analog switch manufactured by Analog Devices/Maxim Integrated. It features a normally closed configuration and operates on an enhanced LC2MOS process. The device supports single-supply operation from +10V to +30V or bipolar supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 35Ω, guaranteed on-resistance matching of 3Ω, and on-resistance flatness of 4Ω. Switching times are limited to 175ns for turn-on and 145ns for turn-off. The component is housed in an 8-pin SOIC package and functions within a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CY' corresponds to the 8-pin SOIC package and the 0°C to +70°C operating temperature range as defined in the official ordering information. Confirm that the component meets RoHS compliance requirements if applicable to the project specifications. Ensure the supply chain source provides valid documentation matching the manufacturer's part number designation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed SPST configuration is required for signal routing applications. The device is suitable for systems requiring rail-to-rail signal handling and low power consumption. Consider the 35Ω maximum on-resistance and switching speeds when designing circuits for high-frequency or precision analog signal paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG417 is part of the DG417/DG418/DG419 family of improved precision analog switches. While the DG418 offers a normally open configuration and the DG419 provides a single-pole/double-throw arrangement, the DG417 specifically delivers a single-channel normally closed switch. All variants share the same LC2MOS fabrication process and core electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies these components as plug-in upgrades for industry-standard DG417/DG418/DG419 devices. Verify pinout compatibility with legacy designs before implementation.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the DG417 switch?

The DG417 is configured as a normally closed (NC) switch.

How does the DG417 handle overvoltage conditions?

Signals on the Source (S) or Drain (D) pins exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added for additional protection if power-supply sequencing is not possible.

What is the maximum analog signal range supported?

The device supports a full analog signal range from V- to V+, allowing for rail-to-rail signal handling within the specified supply voltage limits.
