MAX4906EF 19-0613 Rev 2 3/09 High-/Full-Speed USB 2.0 Switches with High ESD General Description Features The MAX4906EF are electrostatic discharge (ESD)-pro- 15kV (Human Body Model) ESD Protection, tected analog switches that combine low on-capacitance on COM (C ) and low on-resistance (R ) necessary for high- ON ON Fully Specified for a Single +2.7V to +3.6V performance switching applications. The COM inputs Power-Supply Voltage are protected against 15kV ESD without latchup or dam- Low 4 (typ), 7 (max) On-Resistance (R ) age. The device is designed for USB 2.0 high-speed ON applications at 480Mbps. The switches also handle all the -3dB Bandwidth: 500MHz (typ) requirements for USB low- and full-speed signaling. Low Bit-to-Bit Skew 20ps The MAX4906EF features two single-pole/double-throw Charge-Pump Noise = 90V (typ) (SPDT) switches. The device is fully specified to operate from a single +2.7V to +3.6V power supply and is protect- Charge-Pump Enable ed against a +5.5V short to all analog inputs (COM , NC , No Need for Logic-Level Shifters for 1.4V or NO ). This feature makes the MAX4906EF fully compliant Above with the USB 2.0 specification of +5.5V fault protection. COM Analog Inputs Fault-Protected Against The device features a low threshold voltage and a +1.4V Shorts to USB Supply Rail Up to +5.5V V , permitting them to be used with low-voltage logic. IH The device features a QP input that when driven high, Low Supply Current 3A (max) in Standby turns the charge pump off and sets the device in standby Space-Saving 10-Pin, 2mm x 2mm DFN Package mode. When the device is in standby mode, the quies- cent supply current is reduced to 3A (max) and the switches remain operable. Ordering Information The MAX4906EF is available in a space-saving, 2mm x PIN- TOP 2mm DFN package and operates over a -40C to +85C PART TEMP RANGE PACKAGE MARK temperature range.

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.
