DG211CY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211CY is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on dual supplies ranging from 4.5 V to 18 V or a single supply from 9 V to 36 V. The device features a maximum on-resistance of 175 Ohms and supports a DC switch current of 20 mA. Electrical performance includes a maximum turn-on time of 1 µs and a maximum turn-off time of 500 ns. Power dissipation is rated at 696 mW, with a maximum supply current of 400 µA. It is housed in an SOIC-16 surface-mount package and functions within an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST switches within a single CMOS IC for signal routing
• Supports wide dual and single power supply voltage ranges for flexible system integration
• Provides high DC switch current capability for driving moderate loads

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal multiplexing in data acquisition systems
• Audio and video signal path switching
• Instrumentation input selection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CY against official Analog Devices documentation to confirm the commercial grade temperature range and SOIC-16 packaging. Ensure compatibility with required supply voltages and check for RoHS compliance status through authorized distributors. Confirm availability as distribution channels may vary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent analog switches are required in a compact surface-mount format. Verify that the 175 Ohm on-resistance meets circuit requirements. Consider the DG211EUE+ variant if industrial temperature operation (-40°C to +85°C) is necessary instead of the commercial range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG211 belongs to the DG211 family of quad SPST CMOS analog switches. This series provides multiple channel isolation in a single package. The CY suffix denotes the commercial temperature grade and SOIC-16 package type, distinguishing it from other variants like the EUE which offers extended temperature ratings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG211EUE+ serves as a verified alternative offering identical electrical specifications but with an extended industrial temperature range and TSSOP-16 packaging.
