NOTES: A. CL includes probe and jig capacitance.

B. All input pulses are supplied by generators having the following characteristics: PRR

≤ 1 MHz, ZO = 50 Ω, tr ≤ 3 ns, tf ≤

C. The outputs are measured one at a time, with one input transition per measurement.

D. tPHL and tPLH are the same as tpd.
