provides guaranteed minimum
common mode immunity of
100 V/µs while maintaining the
2:1 dynamic range of I
F
.
A recommended layout for use
with an internal 1000
Ω
resistor
or an external pull-up resistor
and required V
CC
bypass capaci-
tor is given in Figure 19. V
CC1
is
used with an external pull-up
resistor for output voltage levels
(V
O
) greater than or equal to 5 V.
As illustrated in Figure 19, an
optional V
CC
and GND trace can
be located between the input and
the output leads of the HCPL-
2300 to provide additional noise
immunity at the compromise of
insulation capability (V
I-O
).
