DG401DY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401DY-T1-E3 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates within a single supply voltage range of 13 V to 36 V or a dual supply range of ±7 V to ±22 V. The device features a maximum on-resistance of 45 Ohms and supports a continuous DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 150 ns and a maximum turn-off time of 100 ns. Power dissipation is rated at 600 mW, with a maximum supply current of 1 uA. It is housed in a 16-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.
