The NMUSB202MC is a surface mount module which conveniently provides
dual port USB data isolation from a single upstream port with full power
(500mA) available from each downstream port. Isolation provides
effective breaking of ground loops and immunity to EMI in harsh
environments as found in industrial and medical applications. Full speed
(12Mbps) and low speed (1.5Mbps) are supported with automatic
switching. Input power of 5V is provided by an external ‘adapter’ or
system voltage rail.
