Description

The MAX14508E—MAX14511E/MAX14509AE high-ESD-protectedDPDT switches multiplex Hi-Speed (480Mbps)USB and analog signals such as AC-coupled audio orvideo. These devices combine the low on-capacitance(CON) and low on-resistance (RON) necessary for high-performance switching applications in portable electronics,and include an internal negative supply to passaudio signals that swing below ground (down to VCC - 5.0V). The MAX14508E—MAX14511E/MAX14509AE alsohandle USB low-/full-speed signaling and operate froma +2.7V to +5.0V supply.The MAX14508E—MAX14511E feature +5.5V fault protectionon COM1 and COM2, making these devicescompliant with the USB 2.0 fault-protection specification.The MAX14510E/MAX14511E feature a VBUS detectioninput (VB) to automatically switch to the USB signal pathupon detection of a valid VBUS signal. The MAX14508E/MAX14510E feature internal shunt resistors on the audio path to reduce clicks and pops heard at the output. The MAX14508E/MAX14509E/MAX14509AE have an enableinput (EN) to reduce supply current and set all channelsto high impedance when driven low.The MAX14508E—MAX14511E/MAX14509AE are availablein a space-saving, 10-pin, 1.4mm x 1.8mm UTQFNpackage, and operate over the -40°C to +85°C temperaturerange.ApplicationsCell PhonesMP3 PlayersNotebook ComputersPDAs
