The 584766-DG403DY is an analog switch integrated circuit from Intersil. It is designed for interface applications and features two SPST (Single-Pole Single-Throw) switch circuits. The on-state resistance of the DG403DY is 45Ohm, and it has a charge injection of 60pC. The switch operates with a single supply voltage ranging from 5V to 34V or a dual supply voltage ranging from ±5V to ±17V. The DG403DY is available in a 16-SOIC package, suitable for surface mount applications. It operates in a wide temperature range from -40°C to 85°C. Although the DG403DY is now obsolete, it was widely used in various analog switch applications due to its low on-state resistance and high crosstalk suppression.
