5. Current Transfer Ratio is defined as a ratio of output collector current, I
O,
to the forward LED input current, I
F
, times 100%.
6. The 4.1 k
$"
load represents 1 LSTTL unit load of 0.36 mA and 6.1k
$"
pull-up resistor.
7. The 1.9 k
$"
load represents 1 TTL unit load of 1.6 mA and 5.6 k
$"
pull-up resistor.
8. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV
cm
/dt on the leading edge of the
common mode pulse signal V
CM
, to assure that the output will remain in a logic high state (i.e., V
O
%
2.0 V). Common mode transient
immunity in logic low level is the maximum tolerable (negative) dV
cm
/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).
9. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted together.
10. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
