The schematic of the ICS8431I-21 layout example used in
this layout guideline is shown in
Figure 5A. The ICS8431I-21
recommended PCB board layout for this example is shown
LAYOUT GUIDELINE
in
Figure 5B. This layout example is used as a general guide-
line. The layout in the actual system will depend on the se-
lected component types and the density of the P.C. board.
