Maxim MAX4890/MAX4891/MAX4892 Ethernet LAN Switch Datasheet
The MAX4890, MAX4891, and MAX4892 are high‑speed analog switches designed for 10/100/1000 Base‑T Ethernet LAN applications. They route signals from two interface transformers to a single Ethernet PHY, simplifying docking‑station designs and supporting board‑level redundancy.
Key features include ultra‑low on‑resistance (4 Ω typ, 6.5 Ω max), ultra‑low on‑capacitance (6.5 pF typ), built‑in LED switches (one for MAX4891, three for MAX4892), and space‑saving 32‑lead and 36‑lead TQFN packages. The devices operate from –40 °C to +85 °C with a supply voltage of 3.0 V to 3.6 V.
