DESCRIPTION
These diode-darlington optocouplers use a light
emitting diode and an integrated high gain photon
detector to provide 2500Volts
RMS
electrical isolation
between input and output. Seperate connection for
the photodiode bias and output darlington collector
improve the speed up to a hundred times that of a
conventional photo-darlington coupler by reducing
the base-collector capacitance.

NOTES:-
1.
Derate linearly above 50
o
C free air temperature at a rate of 0.4 mA/C.
2.
Derate linearly above 50
o
C free air temperature at a rate of 0.7 mW/C.
3.
Derate linearly above 25
o
C free air temperature at a rate of 0.7 mA/C.
4.
Derate linearly above 25
o
C 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).
