DG442DY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DY+T is a quad single-pole single-throw (SPST) analog switch IC 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 85 Ohms and supports a DC switch current of 30 mA. Switching performance includes a maximum turn-on time of 250 ns and a maximum turn-off time of 170 ns. It is housed in a 16-pin SOIC-Narrow package with surface-mount installation, supporting 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 rather than tube packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for the Analog Devices/Maxim Integrated part number to guarantee authenticity and quality standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog channels are required within a compact surface-mount footprint. Compare against similar series members like DG441 or DG444 if different leakage currents or switching speeds are needed. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG44x family of improved quad SPST analog switches. It shares functional similarities with other members like DG441 and DG444 but differs in specific electrical characteristics such as leakage current and switching times. The 'DY+' designation confirms the narrow SOIC-16 package and lead-free construction.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG441DY+T and DG444DY+T are functionally similar quad SPST switches within the same family. Check datasheet parameters for on-resistance and leakage current differences before substitution.
