Figure 11. Thermal derating curve, dependence
of safety limiting value with case temperature
per IEC/EN/DIN EN 60747-5-2.
A recommended layout for use with an internal 1000 Ω
resistor or an external pull-up resistor and required V
CC
bypass capacitor 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
).
