The MAX4989 is a bidirectional 2-of-4 USB 2.0 crosspoint switch. The MAX4989 features the low on-capacitance and low on-resistance necessary to switch USB 2.0 low-/full-/Hi-Speed signals at data rates up to 480Mbps. This device allows any 2-of-4 USB pairs to be connected together and is configured through a simple 3-input control logic interface.
The MAX4989 operates from a single +2.7V to +5.5V supply and features an internal charge pump to permit full rail-to-rail swing. This device also features a high-impedance shutdown mode to reduce supply current to 100nA (typ).
The MAX4989 is available in a 14-pin, 3mm x 3mm TDFN package and operates over the extended -40°C to +85°C temperature range.

Evaluation Kits (1)
The MAX4989 evaluation kit (EV kit) provides a proven design to evaluate the MAX4989 Hi-Speed 2-of-4 USB 2.0 crosspoint switch. The EV kit contains two sub circuits, a typical USB crosspoint switch application (top half), and a test circuit (bottom half).
The USB crosspoint switch application circuit is USB powered by the USB host. USB input/output connectors are also provided to easily interface with USB devices. All USB signal traces are 90Ω differential controlled-impedance traces.
A separate test circuit is also provided at the bottom of the MAX4989 EV kit for eye diagram evaluation using SMA connections and 90Ω controlled-impedance traces.
The MAX4989 EV kit PCB comes with two MAX4989ETD+ devices installed. The MAX4989ETD+ is available in a lead(Pb)-free 14-pin, 3mm x 3mm TDFN package.
