DG401DY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401DY-T is a dual single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 5V to 34V for single supply or ±5V to ±17V for dual supply configurations. The device features a maximum on-resistance of 45 ohms with a channel-to-channel matching of 3 ohms. Switching times are specified at a maximum of 150ns for turn-on and 100ns for turn-off. Key electrical characteristics include a charge injection of 60pC, off-state leakage current of 500pA, and a crosstalk performance of -90dB at 1MHz. It is housed in a 16-SOIC package and supports 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 when sourcing. Confirm RoHS compliance status as older manufacturing runs may differ. Check for obsolescence notices from Renesas, as this component family has faced lifecycle changes. Ensure the supplier provides valid traceability documentation for critical industrial or medical deployments.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated analog channels are required in a compact surface-mount footprint. Compare on-resistance stability against alternative CMOS switches if signal integrity over wide voltage ranges is critical. Verify that the 45-ohm maximum resistance meets the system's voltage drop requirements. Consider the 16-SOIC thermal dissipation capabilities for high-density PCB layouts.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG401 belongs to the broader DG4xx series of monolithic CMOS analog switches produced by Renesas and formerly Maxim Integrated. This series is known for replacing legacy bipolar switch technologies with lower power consumption and higher speed. The DG401 specifically offers a dual-channel solution, contrasting with quad-channel variants like the DG411.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include DG401DYZ. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for updated RoHS compliance in replacement versions.
