The MAX14508E—MAX14511E/MAX14509AE high-ESD-protected 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 high-performance 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 MAX14508E—MAX14511E/MAX14509AE also handle USB low-/full-speed signaling and operate from a +2.7V to +5.0V supply.

The MAX14508E—MAX14511E feature +5.5V fault protection on COM1 and COM2, making these devices compliant with the USB 2.0 fault-protection specification. The MAX14510E/MAX14511E feature a VBUS detection input (VB) to automatically switch to the USB signal path upon 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 enable input (EN) to reduce supply current and set all channels to high impedance when driven low.

The MAX14508E—MAX14511E/MAX14509AE are 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.

Product Detail

The MAX14508E evaluation kit (EV kit) provides a proven design to evaluate the MAX14508E high-ESD-protected double-pole/double-throw (DPDT) switch. The EV kit is designed to demonstrate the MAX14508E used in USB 2.0 Hi-Speed-compliant switching applications. The EV kit routes a multiplexed signal from one USB port to another USB port or an audio connector.

The MAX14508E EV kit PCB comes with a MAX14508EEVB+ installed. Contact the factory for free samples of the pin-compatible MAX14509EEVB+, MAX14510EEVB+, MAX14511EEVB+, or MAX14509AEEVB+ devices.
