The MAX14508 high-ESDprotected DPDT switches multiplex Hi-Speed (480Mbps) USB and analog signals such as AC-coupled audio or video. These devices combine the low on-capacitance (CON) and low on-resistance (RON) necessary for highperformance switching applications in portable electronics, and include an internal negative supply to pass audio signals that swing below ground (down to VCC – 5.0V). The MAX14508 also handle USB low-/full-speed signaling and operate from a +2.7V to +5.0V supply. The MAX14508 feature +5.5V fault protection on COM1 and COM2, making these devices compliant with the USB 2.0 fault-protection specification. The MAX14508E/ MAX14510E feature internal shunt resistors on the audio path to reduce clicks and pops heard at the output. The MAX14508 have an enable input (EN) to reduce supply current and set all channels to high impedance when driven low. The MAX14508 is available in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN package, and operate over the -40°C to +85°C temperature range.
