MAX4983E/MAX4984E 19-4035 Rev 2 9/08 Hi-Speed USB 2.0 Switches with 15kV ESD General Description Features The MAX4983E/MAX4984E are high ESD-protected USB Hi-Speed Switching analog switches that combine the low on-capacitance ESD Protection on COM and low on-resistance necessary for high-performance 15kV Human Body Model switching applications. COM1 and COM2 are protected against 15kV ESD without latchup or damage. The 15kV IEC 61000-4-2 Air Gap devices are ideal for USB 2.0 Hi-Speed applications at 8kV IEC 61000-4-2 Contact 480Mbps. The switches also handle all the require- Power-Supply Range: +2.8V to +5.5V ments for USB low- and full-speed signaling. Low 5 (typ) On-Resistance (R ) ON The MAX4983E/MAX4984E double-pole/double-throw (DPDT) switches are fully specified to operate from a -3dB Bandwidth: 950MHz (typ) single +2.8V to +5.5V power supply and are protected Compatible with Logic I/O Down to 1.4V against a +5.5V short to COM1 and COM2. This feature makes the MAX4983E/MAX4984E fully compliant with COM Analog Inputs Fault Protected Against the USB 2.0 specification of VBUS fault protection. The Shorts to +5.5V devices feature low-threshold-voltage logic inputs, per- Low Supply Current 0.6A (typ) mitting them to be used with low I/O voltage systems. The MAX4983E features an active-low enable input Enable Input: (EN) that when driven high sets the device in shutdown Active-Low (EN) MAX4983E mode. The MAX4984E features an active-high enable Active-High (EN) MAX4984E input (EN) that when driven low sets the device in shut- down mode. When the device is in shutdown mode, the Small 10-Pin, 1.4mm x 1.8mm UTQFN quiescent supply current is reduced to 0.1A. The MAX4983E/MAX4984E are available in a space- saving, 10-pin, 1.4mm x 1.8mm UTQFN package, and Ordering Information operate over a -40C to +85C temperature range.

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 = +2.8V to +5.5V, T = -40C to +85C, unless otherwise noted.
