DG412CY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412CY+T is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10 V to 30 V for single supplies or ±4.5 V to ±20 V for dual supplies. The device features a maximum on-resistance of 80 Ohms and supports a continuous DC switch current of 30 mA. Switching performance includes a maximum turn-on time of 175 ns and a maximum turn-off time of 145 ns. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a 16-pin Narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CY' against official documentation to confirm the commercial grade temperature rating and package variant. Ensure the '+T' designation aligns with the required reel packaging format for surface mount assembly processes. Cross-reference the manufacturer part number directly with Analog Devices records to validate authenticity and current production status before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST topology is required for moderate-speed signal switching applications. The 80 Ohm on-resistance specification suits general-purpose analog signal paths where high precision is not critical. Verify that the 16-pin Narrow SOIC footprint matches the target PCB layout constraints and thermal management requirements for the intended operating environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG411/DG412/DG413 family of improved CMOS analog switches. These components share a redesigned architecture offering enhanced on-resistance matching and flatness compared to earlier generations. The DG412 specifically provides normally open contacts, distinguishing it from the NC DG411 and mixed-contact DG413 variants within the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG412DY+T serves as a verified alternative within the same product family, offering identical electrical characteristics but utilizing a standard SOIC-16 package instead of the Narrow SOIC variant found in the DG412CY+T.
