PC Board Layout
The design of the printed circuit board (PCB) should follow
good layout practices, such as keeping bypass capacitors
close to the supply pins, keeping output signals away from
input signals, the use of ground and power planes, etc. In
addition, the layout of the PCB can also affect the isolation
transient immunity (CMTI) of the ACPL-782T, due primarily
to stray capacitive coupling between the input and the
output circuits. To obtain optimal CMTI performance, the
layout of the PC board should minimize any stray coupling
by maintaining the maximum possible distance between
the input and output sides of the circuit and ensuring that
any ground or power plane on the PC board does not pass
directly below or extend much wider than the body of the
ACPL-782T.
