NOTES: A. C_L includes probe and jig capacitance.
B. All input pulses are supplied by generators having the following characteristics: PRR £ 10 MHz, Z_O = 50 Ω, dv/dt ≥ 1 V/ns.
C. The outputs are measured one at a time, with one transition per measurement.
D. t_PLH and t_PHL are the same as t_pd.
E. V_CCI is V_CCB.
F. V_CCO is V_CCA.
