DG444DY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444DY+T is an improved quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a CMOS construction housed in a 16-pin SOIC-Narrow package with surface-mount installation. The device supports dual supply voltages ranging from ±4.5 V to ±20 V or a single supply of 10 V to 30 V. Key electrical parameters include a maximum on-resistance of 85 ohms, a maximum operating time of 250 ns, and a maximum off-time of 120 ns. It operates within a temperature range of -40°C to +85°C.
