Absolute Maximum Ratings
(T
A
= 25°C unless otherwise noted)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
1. Current Transfer Ratio is defined as a ratio of output collector current, I
O
, to the forward LED input current, I
F
,
times 100%.
2. The 1.9kΩ load represents 1 TTL unit load of 1.6mA and 5.6kΩ pull-up resistor.
3. 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
> 2.0V). 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
< 0.8V).
4. Device is considered a two terminal device: Pins 1, and 3 are shorted together and Pins 4, 5, and 6 are shorted
together.
