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.
The MAX4989 is a USB 2.0 bidirectional crosspoint switch that lets any two of four USB pairs be connected together. It operates from a single +2.7 V to +5.5 V supply, includes an internal charge pump for full rail‑to‑rail swing, and features a high‑impedance shutdown mode that reduces supply current to less than 0.5 µA.
The device is offered in a 14‑pin 3 mm × 3 mm TDFN package and works over an extended temperature range of –40 °C to +85 °C. It provides three control‑logic inputs (C0, C1, C2) and supports data rates up to 480 Mbps with a typical –3 dB bandwidth of 1 GHz.
