MAX4989 19-4206 Rev 0 8/08 USB 2.0 Hi-Speed 2-of-4 Crosspoint Switch General Description Features The MAX4989 is a bidirectional 2-of-4 USB 2.0 cross- Single +2.7V to +5.5V Supply Voltage point switch. The MAX4989 features the low on-capaci- tance and low on-resistance necessary to switch USB Low 1A (typ) Supply Current 2.0 low-/full-/Hi-Speed signals at data rates up to -3dB Bandwidth: 1GHz (typ) 480Mbps. This device allows any 2-of-4 USB pairs to be connected together and is configured through a Low 5 (typ) R ON simple 3-input control logic interface. The MAX4989 operates from a single +2.7V to +5.5V High-Impedance Shutdown Mode supply and features an internal charge pump to permit Logic Inputs Control Signal Routing full rail-to-rail swing. This device also features a high- impedance shutdown mode to reduce supply current to +1.8V CMOS-Logic Compatible 100nA (typ). The MAX4989 is available in a 14-pin, 3mm x 3mm Ultra-Small 14-Pin, 3mm x 3mm, TDFN Package TDFN package and operates over the extended -40C to +85C temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = +2.7V to +5.5V, T = -40C to +85C, unless otherwise noted.
