DG442DY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DY-T1 is a CMOS analog switch IC manufactured by Vishay Siliconix, housed in a 16-pin SOIC surface-mount package. It integrates four independent single-pole single-throw (SPST) channels. The device operates with a dual supply voltage of ±15 V and supports single supply configurations. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum power dissipation of 900 mW, and a maximum supply current of 100 uA. Switching performance features a maximum turn-on time of 250 ns and a maximum turn-off time of 120 ns. The component functions within an operating temperature range of -40°C to +85°C.
