_1 Ctr is defined as the ratio of the Output Collector current (Io) to the LED Forward Current ( If ), times 100%.
_2 Device is considered a two terminal device. Pins 1 and 2 are shorted together and pins 4,and 5 are shorted
together.
_3 Measured between the LED cathode and pins 4 and 5 (shorted together).
_4 Parameters shall be tested as part of the device's initial characterization . Parameters are guaranteed to the limits
specified for all lots not specifically tested.
_5 Cmh is the maximum common mode transient to assure that the output will remain in a high logic state (Vo > 2.0V).
_6 In applications where dV/dt may exceed 50,000 Vs a series resistor must be included in the Vcc line to limit
destructively high surge currents. The recomended value, at If = 0.5mA, is 3.3K
_7 Cml is the maximum common mode transient to assure that the output will remain in a low logic state (Vo < 0.8V).
