What is an inherent problem to watch out for when adding transient suppressors to data lines?
Much of the electrical equipment seen today in facilities and in
some homes is built on
integrated circuit and microprocessor technology. Because of
certain characteristics common
to integrated circuits and microprocessors, this equipment is
especially sensitive to transient
voltage surges. Microprocessor based and controlled devices can be
found in almost every
setting. Some of this electronic equipment includes computers and
their peripherals,
computer and data networks (such as LANs), telecommunications
equipment, medical
diagnostic equipment, CNC production machinery, radio equipment,
televisions, satellite
television equipment, electronic cash registers, copy machines, fax
machines, etc. Much of
this equipment is also commonly found connected to some form of
data line for communica-
tion purposes.
The three factors which contribute to transient sensitivity of IC
(integrated circuit) based
machines are:
1. The spacing of IC and circuit board traces
2. The applied operating voltage limit
3. The use of a clock cycle to synchronize certain operations (such
as in computers)
