The MAX4999ETJ+ is an USB 2.0 high speed differential 8:1 multiplexer in 32 pin TQFN package. The differential high speed USB analogue 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.
Supply voltage range is 3V to 3.6V
Operating temperature range from -40°C to 85°C
1200MHz of -3dB bandwidth
On-resistance (RON) is 6.5ohm (typ)
Low operating current (1μA) and ultra low quiescent current (30nA) in standby mode
Low threshold eliminates the need for translators in 1.8V low-voltage systems
