DG408DYZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408DYZ is a CMOS analog multiplexer manufactured by Renesas Electronics, housed in a 16-pin SOIC surface-mount package. It features an 8x1 channel configuration with a single output. The device supports supply voltages ranging from 5V to 34V and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum on-resistance of 100Ω, an on-delay time of 180ns, and an off-delay time of 120ns. Supply current specifications are listed as 10μA and 200μA under different conditions, with a propagation delay of 250ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation carefully, as DG408 devices are produced by both Renesas Electronics and Vishay. Confirm that the specific part number suffix matches the required packaging and compliance standards. Check datasheet revisions to ensure pinout and electrical characteristics align with design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer is required in a compact SOIC-16 footprint. Ensure the application voltage does not exceed the 34V maximum rating. Consider the 100Ω on-resistance and 250ns propagation delay against system timing constraints. Verify thermal management needs for the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG40x series of analog switches and multiplexers. The series includes variants such as the DG403 (SPDT switch), DG406 (16:1 mux), and DG409 (differential mux). The DG408DYZ specifically provides 8-input selection capability using standard CMOS logic levels for control signals.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG408DY is a tube-packaged equivalent. DG408LEDY-GE3 is a Vishay variant with potentially different electrical limits (16V max voltage). DG408LDY-T1-E3 is a discontinued Vishay alternative.
