DG442CY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442CY+T is a quad single-pole single-throw (SPST) CMOS analog switch IC manufactured by Analog Devices Inc. and Maxim Integrated. It features four independent channels in a 16-SOIC surface-mount package. The device supports dual supply voltages ranging from ±4.5 V to ±20 V, or a single supply of 10 V to 30 V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum power dissipation of 696 mW, and a maximum supply current of 100 uA. Switching times are specified with a maximum turn-on time of 250 ns and a maximum turn-off time of 170 ns. The component operates within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm that the manufacturer designation aligns with current Analog Devices or Maxim Integrated production lines. Ensure the order specification matches the required 16-SOIC package dimensions and lead frame finish for proper PCB footprint compatibility during procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance specifications. Verify that the operating voltage range of 10 V to 30 V single supply meets system requirements. Consider the 85 Ohm on-resistance limit for signal integrity constraints. Ensure the thermal performance of the SOIC package accommodates the 696 mW power dissipation under expected load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG442 series of improved quad SPST analog switches. It shares functional similarities with other members like the DG441 and DG442 variants, differing primarily in packaging options such as tube versus tape-and-reel. The device is part of the broader Maxim Integrated analog switch portfolio designed for general-purpose signal switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers include DG442CY, DG442CY-, and DG442DY+. These alternatives share identical electrical characteristics but may differ in packaging format or manufacturing lot specifications. Verify pinout compatibility before substitution.
