DG403EY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403EY is a quad single-pole single-throw (SPST) analog switch manufactured by Harris Corporation, part of the DG series. It features four independent channels in a 16-pin SOIC package. The device supports dual supply voltages ranging from ±7V to ±22V and single supplies up to 36V. Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum switching time of 150 ns, and an off-time of 100 ns. It operates within a temperature range of -40°C to +85°C with a maximum power dissipation of 600 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific suffix variations against current datasheets before procurement. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog signal paths are required in a compact surface-mount format. Verify that the 45 Ohm on-resistance meets system accuracy requirements. Ensure the operating voltage range aligns with the available power rails and that the thermal dissipation capabilities are sufficient for the expected load currents.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG401/403/405B family of analog switches. The DG403 variant specifically provides four SPST channels, distinguishing it from the DG401 (two channels) and DG405 (eight channels). The EY suffix typically denotes a specific package and temperature grade configuration within the broader product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Compatible substitutes include the DG403BDY-T1-E3 and DG403BDY. Verify pin compatibility and electrical specifications such as on-resistance and supply voltage limits before substitution.
