NOTES: A. CL includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions such that the output is low except when connected to the internal 500-Ω
pulldown resistor. Waveform 2 is for an output with internal conditions such that the output is high except when connected to the
internal 500-Ω pulldown resistor.
C. All pulse inputs and DC inputs are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50 Ω,
tr ≤ 2.5 ns, tf ≤ 2.5 ns.
D. The outputs are measured one at a time with one transition per measurement.
E. tPLZ and tPHZ are the same as tdis. Z = RINT = 500 Ω
F. tPZL and tPZH are the same as ten. Z = RINT = 500 Ω
G. tPLH and tPHL are the same as tpd.
