DG212CY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG212CY+ is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 9 V to 36 V for single supplies, or ±4.5 V to ±18 V for dual supplies. The device features a maximum on-resistance of 175 Ohms and supports a DC switch current of 20 mA. Switching times include a maximum turn-on time of 1 µs and a maximum turn-off time of 500 ns. It is housed in a 16-pin SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CY' against official Analog Devices documentation to confirm temperature grade and packaging details. Ensure compatibility with required supply voltages and load conditions before integration. Cross-reference datasheet electrical characteristics for precise on-resistance and leakage specifications relevant to the application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent analog switches are required within a single package. Consider the 175 Ohm on-resistance limit and 20 mA current handling capacity against circuit requirements. Verify that the 9 V minimum supply voltage aligns with available system rails, as lower voltage operation may not be supported compared to other CMOS switch families.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG212 series belongs to the broader family of CMOS analog switches from Maxim Integrated. These devices are designed for general-purpose signal switching applications. The DG212 variant specifically offers quad SPST functionality, distinguishing it from dual or octal configurations within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official Analog Devices substitution guides for verified equivalents. Generic replacements may differ in on-resistance, leakage current, or supply voltage ranges. Verify pinout compatibility and thermal performance before substituting.
