NMFAAAA Product Preview USB Clamps, RS232 and General Purpose Data Line Filters with ESD Protection; Optional Internal Switch http://onsemi.com USB line clamps (DOUT+, DOUT ) protect low operating voltage loads.

Five additional low pass filters are built in to reject RF noise and EMI on RS232 and GP data lines.

When the USB lines are used, a switch is utilized to open the RS232 lines in order to reduce the loading on the USB lines.

There are two options available for this device.
