NOTES:-
1.
Derate linearly above 50oC free air temperature at a rate of 0.4 mA/°C.
2.
Derate linearly above 50oC free air temperature at a rate of 0.7 mW/°C.
3.
Derate linearly above 25oC free air temperature at a rate of 0.7 mA/°C.
4.
Derate linearly above 25oC free air temperature at a rate of 2.0 mW/°C.
5.
CURRENT TRANSFER RATIO is defined as the ratio of output collector current,I
O , to the forward LED
input current, I
F multiplied by 100%.
6.
Pin 7 open.
7.
Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted
together.
8.
Use of a resistor between pin 5 and 7 will decrease gain and delay time.
9.
Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVcm/dt on
the leading edge of the common mode pulse V
CM to assure that the output will remain in a Logic High
state (i.e. V
O > 2.0V). Common mode transient immunity in Logic Low level is the maximum tolerable
(negative) dVcm/dt on the trailing edge of the common mode pulse signal, V
CM to assure that the output
will remain in Logic Low state (i.e. V
O< 0.8V).
