DG403BDY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403BDY-T1-E3 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It features four independent SPST switches in normally open/normally closed combinations within a 16-pin narrow SOIC package. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a typical on-resistance (RDS(on)) of 23 Ω with a maximum of 45 Ω, turn-on time of 100 ns, and turn-off time of 60 ns. It operates within a temperature range of -40 °C to +85 °C.
