Filter connectors or transzorbs should be used to reduce
the RFI/EMI, protecting the system from static (ESD), and
electrical overstress (EOS). A filter connector or capacitor
will reduce the ESD pulse by 90% typically. A cable
dragged across a carpet and connected to a system can
easily be charged to over 25,00 volts. This is a metal to
metal contact when the cable is connected to the system
(no resistance), currents exceed 80 amps with less than a
nanosecond rise time. A transzorb provides two functions,
the device capacitance inherently acts as a filter capaci-
tor, and the device clamps the ESD and EOS pulses
which would pass through the capacitor and destroy the
devices. The recommended transzorb for the UC5170C is
P6KEIOCA.

Industries.
SPECIFIC LAYOUT NOTES
The UC5170C layout must have bulk bypassing close to
the device. Peak slew current is greater than 500mA
when all eight drivers slew at once in the same direction.
Some applications mount the UC5170C on a bulkhead or
isolated plane for RFI/FCC/VDE reasons. If bulk bypass-
ing is not used, the -10V supply may go above -8.5 volts,
causing the slew rate control circuit to become unstable.
The UC5170C can have output oscillation at 100kHz if
the +10V supply is applied before the -10V supply. This
has been a problem in some terminal designs where the
+10V was developed from the flyback, which can result in
a 500ms difference in the application of the supplies at
power up.
GENERAL LAYOUT NOTES
The drivers and receivers should be mounted close to the
system common ground point, with the ground reference
tied to the common point to reduce RFI/EMI.
