DG417LEUA

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417LEUA+ is a single-channel, normally-closed SPST analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a single supply voltage range of 9V to 36V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 35 ohms and supports a continuous DC current of 30 mA. Key timing specifications include a maximum turn-on time of 175 ns and a maximum turn-off time of 185 ns. It is housed in an 8-UMAX surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Normally-closed (NC) configuration for fail-safe signal path maintenance
• Low power consumption with 1 uA maximum supply current
• High isolation performance with low off-state leakage current
• Compatible with standard logic control levels

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring normally-closed signal paths
• Battery-powered instrumentation due to low quiescent current
• Industrial process control signal routing
• Medical equipment signal conditioning

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'LEUA' against official datasheets to confirm the UMAX-8 package and industrial temperature grade. Ensure compatibility with existing PCB footprints for this small outline package. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed state is required upon power loss or control signal absence. Compare the 35 ohm on-resistance against circuit tolerance requirements. Verify that the 30 mA continuous current rating exceeds the maximum load current in the application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG417 family of improved SPST analog switches. The family includes variants such as DG417LDY+ and DG417CY+T, which share similar electrical characteristics but differ in packaging and shipping formats. The LEUA variant specifically denotes the UMAX-8 surface-mount construction.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include DG417LDY+ and DG417CY+T for equivalent electrical performance in different packages. For normally-open configurations, consider the DG411 series. Always verify pinout compatibility and thermal dissipation limits when substituting.
