MAX4999_11 Overview

USB 2.0 Hi-Speed Differential 8:1 Multiplexer Small 32-Pin, 5mm x 5mm, TQFN Package

19-4127; Rev 1; 6/11
USB 2.0 Hi-Speed Differential
8:1 Multiplexer
General Description
The MAX4999 differential Hi-Speed USB analog multi-
plexer features low on-capacitance (C
ON
) 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 sup-
porting data rates up to 480Mbps.
The MAX4999 is a differential 8:1 multiplexer. The
MAX4999 features three digital inputs to control the sig-
nal 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 mini-
mum power consumption.
The MAX4999 operates from a +3.0V to +3.6V power-
supply voltage and is specified over the -40°C to +85°C
extended temperature range. The MAX4999 is available
in a 5mm x 5mm, 32-pin TQFN package.
