_1 Each Channel
_2 Ctr is defined as the ratio of the Output Collector current (Io) to the LED Forward Current ( If ), times 100%.
_3 If = 2A for channel under test, All other channels, If = 10mA.
_4 Device is considered a two terminal device. Pins 1 thru 10 are shorted together and pins 11 thru 20 are shorted
together.
_5 Measured between the LED cathode and pins 11 through 20 (shorted together).
_6 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.
_7 Cmh is the maximum common mode transient to assure that the output will remain in a high logic state
(Vo > 2.0V).
_8 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
_9 Cml is the maximum common mode transient to assure that the output will remain in a low logic state
(Vo < 0.8V).
