DG441CY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441CY+T is a quad single-pole single-throw normally-closed analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10V to 30V for single supplies or ±4.5V to ±20V for dual supplies. The device features a maximum on-resistance of 85 Ohms, with switching times of 250ns (Ton) and 120ns (Toff). Key electrical characteristics include a charge injection of 5pC, channel capacitance of 4pF, and leakage current of 500pA. It is housed in a 16-SOIC surface-mount package and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceable origin data matching the Analog Devices/Maxim Integrated branding to avoid counterfeit risks during procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed state is required for multiple independent channels. Compare against the DG411 series if lower on-resistance or extended temperature ranges are necessary. Verify that the 85 Ohm resistance and 500pA leakage meet system requirements before finalizing the design choice.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG441 family of improved quad SPST analog switches. It shares functional similarities with other members like the DG441DJ+, differing primarily in package type and manufacturing lot specifications. The '+T' designation specifically identifies the reel packaging format for surface-mount technology applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG441DJ+ serves as a pin-compatible alternative in a 16-PDIP through-hole package. Designers requiring different thermal profiles or mounting styles should verify mechanical fitment before substitution.
