CL includes probe and jig capacitance.
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.
I/Os are configured as inputs.
All parameters and waveforms are not applicable to all devices.
