DG441BDY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441BDY-T1 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It operates on single or dual supplies, with a maximum supply voltage of 36 V (single) or ±18 V (dual). The device features a typical on-resistance of 45 Ω and a maximum of 80 Ω at room temperature. Switching times are specified as 220 ns for turn-on and 120 ns for turn-off. Power consumption is low at 1 mW, with a maximum supply current of 1 µA. The operating temperature range spans from -40 °C to +85 °C.
