USB Clamps, RS232 and
General Purpose Data Line
Filters with ESD Protection;
Optional Internal Switch
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. NMFAAAA−1 has the switch external, and NMFAAAA−2
integrates the switch on chip. Also, when the switch is integrated, the
USB line resistors are integrated as well.
