Limit data for +125 C applies to P82B96TD/S410 version. It is guaranteed by design/characterization, but not by 100 % test.
The minimum value requirement for pull-up current, 200 A, guarantees that the minimum value for V
the minimum V
While the tolerances on absolute levels allow a small probability the LOW from one Sx output is recognized by an Sx input of another
P82B96, this has no consequences for normal applications. In any design the Sx pins of different ICs should never be linked because
the resulting system would be very susceptible to induced noise and would not support all I
The output logic LOW depends on the sink current. For scaling, see Application Note AN255 .
The input logic threshold is independent of the supply voltage.
