DG403DY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403DY-T is a dual single-pole double-throw (SPDT) analog switch manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 5 V to 34 V for single supplies or ±2.5 V to ±17 V for dual supplies. The device features a maximum on-resistance of 45 Ohms and supports switching speeds with a maximum turn-on time of 150 ns and turn-off time of 100 ns. It is housed in a 16-pin SOIC-Narrow package and functions reliably across an industrial 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 through official manufacturer documentation, as legacy variants may differ. Ensure the supplier provides valid traceability for the Renesas brand. Cross-reference the full part number against current datasheets to confirm pinout and electrical specifications match the design requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring bilateral signal handling with low leakage current. Compare the 45 Ohm on-resistance against load requirements to ensure acceptable voltage drop. Verify that the 150 ns switching speed meets the system timing constraints. Consider the 16-SOIC package dimensions for PCB layout compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG403 series of monolithic CMOS analog switches.
