The MAX4999 differential Hi-Speed USB analog multiplexer features low on-capacitance (CON) switching, making it an ideal solution for the USB server/mass storage market. The MAX4999 is designed for USB 2.0 low-/full-/Hi-Speed applications with capability of supporting data rates up to 480Mbps. The MAX4999 is a differential 8:1 multiplexer. The MAX4999 features three digital inputs to control the signal path. Typical applications include switching a USB connector between eight USB hosts and a USB device. An enable input (EN) is provided to disable all channels and place the device into a high-impedance state (standby mode), shutting off the charge pump for minimum power consumption. The MAX4999 operates from a +3.0V to +3.6V powersupply voltage and is specified over the -40C to +85C extended temperature range. The MAX4999 is available in a 5mm x 5mm, 32-pin TQFN package.
