MAX14531EMAX14534E 19-4597 Rev 0 4/09 USB 2.0 Hi-Speed and Audio Switches with Negative Signal Capability and 15kV ESD General Description Features The MAX14531EMAX14534E high ESD-protected Single +2.7V to +5.5V Supply Voltage DP3T switches multiplex Hi-Speed (480 Mbps) USB Low 10A (typ) Supply Current signals, low/full-speed USB signals, and analog sig- nals such as AC-coupled audio or video through any -3dB Bandwidth: 800MHz (typ) of three channels. These devices combine the low on- Low 2 (typ) On-Resistance capacitance (C ) and low on-resistance (R ) nec- ON ON essary for high-performance switching applications in 0.05% THD+N portable electronics, and include an internal negative Internal Shunt Resistor for Click-and-Pop supply to pass AC-coupled audio signals that swing below ground (down to -2.0V). The MAX14531E Reduction (MAX14532E/MAX14534E) MAX14534E operate from a +2.7V to +5.5V supply. VBUS Detection for Automatic Switch Path The MAX14531EMAX14534E have a shutdown func- Selection tion to reduce supply current and set all channels to +28V Maximum Rated VBUS Detection Input high impedance. The MAX14531EMAX14534E feature (CB0) a VBUS detection function through the CB0 input to Space-Saving, 12-Bump, 1.5mm x 2.0mm WLP automatically switch to the default USB signal path upon detection of a valid VBUS signal. The Package MAX14532E/MAX14534E feature internal shunt resis- Pin Configuration tors on audio channels to reduce clicks and pops heard at the output. The MAX14531EMAX14534E are available in a space- TOP VIEW (BUMPS ON BOTTOM) saving, 12-bump, 1.5mm x 2.0mm WLP package and operate over the -40C to +85C temperature range. 1 23 4 Applications + MAX14531E/MAX14532E/ Cell Phones MAX14533E/MAX14534E MP3 Players A CB0 UAZ1 UAZ2 COM1 PDAs Notebook Computers B V UAX1 UAX2 GND CC C CB1 UAY1 UAY2 COM2 WLP Ordering Information/Selector Guide PART PIN-PACKAGE SHUNT RESISTORS CB0 PULLDOWN RESISTOR TOP MARK MAX14531EEWC+ 12 WLP NONE No AAT MAX14532EEWC+ 12 WLP UAZ Yes AAU MAX14533EEWC+* 12 WLP NONE Yes AAV MAX14534EEWC+* 12 WLP UAY /UAZ Yes AAW Note: All devices are specified over the -40C to +85C operating temperature range. +Denotes a lead(Pb)-free/RoHS-compliant package. *Future productcontact factory for availability.

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 = +2.7V to +5.5V, T = -40C to +85C, unless otherwise noted.
