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/HCPL-0300 to
provide additional noise
immunity at the compromise of
insulation capability (V_I-O).
