DG409DY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409DY+T is an improved CMOS analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features a dual 4:1 configuration, providing two independent SP4T switches within a single 16-pin SOIC package. The device operates with a single supply voltage ranging from 5 V to 30 V or dual supplies of ±5 V to ±20 V. Key electrical specifications include a maximum on-resistance of 175 Ohms, a maximum turn-on time of 600 ns, and a maximum turn-off time of 300 ns. It supports a power dissipation of 696 mW and functions within a temperature range of -40°C to +85°C.
