Electrostatic Protection
(Note)
When correctly designed for ESD protection, SCRs can be
highly effective, enabling circuits to be protected to well in
excess of 4kV. The SCR ESD-EOS protection structures used
on each terminal of the CA3224E are shown schematically in
either Figures 6A or 6B. Although ESD-EOS protection is
included in the CA3224E, proper circuit board layout and
grounding techniques should be observed.
NOTE: For further information on CA3224E protection structures refer
to: AN7304, “Using SCRs as Transient Protection Structures in
Integrated Circuits”, by L.R. Avery. Intersil AnswerFAX (407-724-7800)
document #97304.
