NOTES: A. CL includes probe and jig capacitance.

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

≤ 10 MHz, ZO = 50 Ω, tr = 3 ns, tf = 3 ns. For testing

fmax and pulse duration: tr = 1 to 3 ns, tf = 1 to 3 ns.

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