PRODUCT OVERVIEW
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 must be provided by an external ‘adapter’ or system voltage rail.
The input power of 5V provided to the hub cannot be sourced from a USB connection.
