Current transfer ratio in percent equals the ratio of output collector current (I
O
) to the forward LED input current (I
F
) times 100.
Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.
Common mode transient immunity in a Logic High level is the maximum tolerable (positive) dV
/dt on the leading edge of the com-
mon 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 a 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 a Logic Low state (i.e., V
O
<0.8 V).
The 1.9 K
load represents 1 TTL unit load of 1.6 mA and the 5.6 k
pull-up resistor.
The 4.1 K
load represents 1 LSTTL unit load of 0.36 mA and the 6.1 k
pull-up resistor.
A 0.1
μ
f bypass capacitor connected between pins 5 and 8 is recommended.
