The MAX4989ETD+T is a bidirectional USB 2.0 hi-speed 2 of 4 crosspoint switch in 14 pin TDFN package. It has 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 simple 3 input control logic interfaces. 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.
