High-Speed, 2-of-4 Crosspoint Switch Handles USB 2.0 Data Rates
Note to Editor:
- The MAX4989 is a bidirectional, 2-of-4, USB 2.0 crosspoint switch.
- This device allows any 2 out of 4 combinations of USB pairs to be switched at one time, thus enabling multiple USB host devices to be switched simultaneously.
- This performance is enabled by the MAX4989's low-on-resistance and low-on-capacitance switching architecture.
- The MAX4989 is an ideal solution for notebook and cell phone applications.

SUNNYVALE, CA—October 23, 2008—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX4989, a bidirectional, 2-of-4, USB 2.0 crosspoint switch. This device switches any 2 of 4 USB pairs while supporting data rates up to 480Mbps, thus enabling multiple USB host devices to be switched simultaneously. To enable this performance, the MAX4989 features 5.0Ω (typ) on-resistance and low, 6.0pF (typ) on-capacitance switching architecture. Additionally, an integrated charge pump improves performance, providing the full rail-to-rail swing necessary to support Hi-Speed USB applications, making it also compatible with Original USB. This combination of features makes the MAX4989 ideal for applications such as notebooks and cell phones.
To minimize power consumption, the MAX4989 provides three control-logic inputs that can all be driven high or low to place the device in shutdown mode. Shutdown mode reduces the supply current to less than 0.5µA and places all switch terminals in high impedance.
The MAX4989 operates from a single 2.7V to 5.5V supply, and is fully specified over the -40°C to +85°C extended temperature range. The device is available in an ultra-small, 3mm x 3mm, 14-pin TDFN package. Prices start at $1.50 (1000-up, FOB USA).
