Notes
1. DC current transfer ratio is defined as the ratio of outpput collector current, I
O
, to the forward LED input current, I
F
times 100%.
2. Pin 7 open.
3. Device considered a two-terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7 and 8 shorted together.
4. Using a resistor between pin 5 and 7 will decrease gain and delay time.
5. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV
/dt on the leading edge of the commo-
mode pulse, V
, to assure that the output will remain in a logic high state (i.e. V
>2.0 V) common mode transient immunity in logic
low level is the maximum tolerable (negative) dV
/dt on the trailing edge of the common mode puse signal, V
CM
, to assure that the
output will remain in a logic low state (i.e. V
O
<0.8 V).
6. In applications where dv/dt may exceed 50,000 V/
μ
s (such as state discharge) a series resistor, R
should be included to protect IC
from destructively high surge currents. The recommended value is
R
CC
IV k
.
