DG401BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401BDJ is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It contains two independent single-pole single-throw (SPST) switches housed in a 16-pin plastic dual-in-line package. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a maximum on-resistance of 45 Ω at room temperature and up to 55 Ω across the full operating temperature range. Turn-on time is typically 100 ns with a maximum of 150 ns, while turn-off time is typically 60 ns with a maximum of 100 ns. The device operates within a temperature range of -40 °C to +85 °C.
