Vishay DG408L/409L Analog Multiplexer Datasheet
The DG408L/409L family provides precision analog switching for data‑acquisition, portable test equipment, and communication systems. They are pin‑for‑pin compatible with the DG408/409 series but offer lower on‑resistance, faster switching times, reduced leakage, and higher off‑isolation. Both single‑supply (2.7 V‑12 V) and dual‑supply (+3 V‑+6 V) operation are supported.
Typical applications include sample‑and‑hold circuits, battery‑operated devices, and audio/video signal routing. The datasheet includes functional block diagrams, pin configurations, truth tables, ordering information, absolute maximum ratings, and extensive electrical specifications for various supply conditions.
