CL includes probe and
jig capacitance.
tpv is measured from
0.7 × VCC on SCL to 50% I/O (Pn) output.
All inputs are supplied by
generators having the following characteristics: PRR ≤ 10 MHz, ZO =
50 Ω, tr/tf ≤ 30 ns.
The outputs are measured one at a
time, with one transition per measurement.
All parameters and waveforms are
not applicable to all devices.
