(1)
Typical value is at VCC = 2.5 V, TA = 25°C
(2)
See the Typical Characteristics section of this data sheet.
(3)
The output logic low depends on the sink current.
(4)
The input logic threshold is independent of the supply voltage.
(5)
The minimum value requirement for pullup current, 200
μA, ensures that the minimum value for VSX output low always exceeds the
minimum VSx input high level to eliminate any possibility of latching. The specified difference is specified by design within any device.
While the tolerances on absolute levels allow a small probability that 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 devices should never be linked,
because the resulting system would be very susceptible to induced noise and would not support all I2C operating modes.
