1) Operating Precautions
‘\ (1) Precautions for Input Voltage
All input and output terminals are connected for direct coupled circuitry. Do not apply
external
voltage
to
any
output
terminal.
The
output
terminal
(9)
provides
a
maximum
instantaneous
input
voltage
of
d:
SV
(AC+DC).
Consequently,
if
the
voltage
applied
to
the
terminal
exceeds
this
value,
the
internal
circuitry
will
be
damaged.
