DG211DY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211DY+T is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent channels in a 16-pin SOIC narrow package. The device operates on dual supplies ranging from ±4.5 V to ±18 V, or a single supply from 9 V to 36 V. Key electrical parameters include a maximum on-resistance of 175 Ohms, a maximum power dissipation of 696 mW, and a maximum supply current of 400 uA. Switching times are specified with a maximum turn-on time of 1 us and a maximum turn-off time of 500 ns. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. / Maxim Integrated to ensure authenticity. Check RoHS compliance status through official datasheets or distributor documentation prior to integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPST switches are required in a surface-mount format. Ensure the system voltage aligns with the 9V to 36V single supply or ±4.5V to ±18V dual supply limits. Consider the 175 Ohm on-resistance limit for signal integrity requirements. Verify thermal management capabilities given the 696 mW power dissipation rating in the SOIC-16 package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG211 series of quad SPST analog switches. It shares functional similarities with other members like the DG211CSE+T and DG211CY+, differing primarily in packaging type such as SOIC, TSSOP, or PDIP. The series is designed for general-purpose analog switching tasks requiring moderate speed and robust supply voltage tolerance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives within the same family include DG211EUE+ and DG211CY+. Verify package dimensions and thermal characteristics when substituting between SOIC, TSSOP, or tube/reel variants.
