MAX4906/MAX4606F/MAX4907/MAX4907F 19-3797 Rev 2 1/07 High-/Full-Speed USB 2.0 Switches General Description Features The MAX4906/MAX4906F/MAX4907/MAX4907F analog Fully Specified for a Single +3.0V to +3.6V switches combine the low on-capacitance (C ) and ON Power-Supply Voltage low on-resistance (R ) necessary for high-perfor- ON Low 4 (typ), 7 (max) On-Resistance (R ) ON mance switching applications. These devices are MAX4907/MAX4907F Ultra-Low 4pF (typ), designed for USB 2.0 high-speed applications at 480Mbps. These switches will also handle all the 7pF (max) On-Capacitance (C ) ON requirements for USB low- and full-speed signaling. -3dB Bandwidth: 1GHz (typ) The MAX4906/MAX4906F feature two single-pole/dou- Low Bit-to-Bit Skew 100ps ble-throw (SPDT) switches, and the MAX4907/ Shutdown Input Reduces Power Consumption MAX4907F feature two single-pole/single-throw switches to 2A (max) (SPST). The MAX4907/MAX4907F have a low 7 (max) 3.3V, 1.8V, and 1.4V Logic Compatible on-resistance and 7pF (max) on-capacitance. These devices are fully specified to operate from a single COM Analog Inputs Fault Protected Against +3.0V to +3.6V power supply and are protected against Shorts to USB Supply Rail Up to +5.5V a +5.5V short to COM1 and COM2. This feature makes Space-Saving Packages them fully compliant with the USB 2.0 specification of 8-Pin and 10-Pin, 2mm x 2mm DFN Packages +5.5V fault protection. These devices feature a low threshold voltage and a +1.4V V , permitting them to IH be used with low-voltage logic. The MAX4906/ MAX4906F/MAX4907/MAX4907F operate at 300A (max) quiescent current and feature a shutdown input Ordering Information to reduce the quiescent current to less than 2A (max).

Limit forward-diode current to maximum current rating. 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+ = +3V to +3.6V, T = T to T , unless otherwise noted.
