DG417CY

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.

Feature Summary

Guaranteed low charge injection of 10pC maximum
Low off-leakage current performance below 5nA at +85°C
High electrostatic discharge tolerance of 2000V minimum per Method 3015.7
TTL and CMOS logic compatible input levels

Applications

Sample-and-Hold Circuits
Precision Test Equipment
Battery-Operated Systems
Audio Signal Routing

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.

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.

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.

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.

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.
