5 / 6 page 5 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 re- fer to: AN7304, “Using SCRs as Transient Protection Structures in In- tegrated Circuits”, by L.R. Avery. NOTE: 3. One of three identical driver circuits shown. FIGURE 4.
