DG403DY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403DY-T1-E3 is a CMOS analog switch integrated circuit manufactured by Vishay Siliconix. It features four independent single-pole single-throw (SPST) switches housed in a 16-pin SOIC package. The device supports single supply voltages ranging from 13 V to 36 V or dual supplies of ±7.5 V to ±22 V. Key electrical parameters include a maximum on-resistance of 45 Ohms, a power dissipation of 600 mW, and a maximum supply current of 1 µA. Switching times are specified with a maximum turn-on time of 150 ns and a maximum turn-off time of 100 ns. The component operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1-E3 to confirm tape-and-reel packaging and RoHS compliance status. Confirm availability as distribution data indicates potential stock limitations. Ensure the 16-SOIC footprint matches the target PCB layout constraints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog channels are required within a single IC footprint. Compare on-resistance and leakage specifications against alternative DG series parts if lower resistance is needed. Verify that the 13 V minimum single-supply requirement aligns with the target system voltage rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG40x series of CMOS analog switches from Vishay Siliconix. The series is characterized by high speed and low power consumption. The DG403 variant specifically provides four SPST channels, distinguishing it from dual-channel or multiplexer variants within the same family.
