Maxim MAX4887 Triple Video Switch Datasheet
The MAX4887 is a triple, high‑frequency video switch intended for notebook computers, monitors, docking stations, and similar applications. It routes RGB signals between one driver and two loads (1:2) or between two sources and one load (2:1) using three SPDT analog switches. The device uses an internal low‑noise charge pump to provide a high‑drive pull‑up, achieving low on‑resistance (≈5 Ω) and low on‑capacitance (≈10 pF) for high‑speed video signals.
The datasheet provides absolute maximum ratings, detailed electrical characteristics for 5 V and 3.3 V supplies, pin descriptions, layout recommendations, and ESD protection information. The part is supplied in a 3 mm × 3 mm, 16‑pin thin‑QFN package with an exposed paddle for grounding and is rated for operation from –40 °C to +85 °C.
