The DG535 is a monolithic CMOS Quad SPST (Single-Pole, Single-Throw) analog switch manufactured by Vishay. Designed for high-performance analog signal switching, it features low on-resistance and charge injection. Being an End-of-Life (EOL) component, the DG535 is typically used in maintaining legacy systems or for replacements where a direct substitute is required without significant redesign.
