SETUP AND HOLD TIMES
A. C_L includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output
control. Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the
output control.
C. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Z_O = 50 Ω, for
propagation delays t_r/t_f = 3 ns, for setup and hold times and pulse width t_r/t_f = 1.2 ns.
D. The outputs are measured one at a time, with one transition per measurement.
E. t_PLH and t_PHL are the same as t_pd.
F. All parameters and waveforms are not applicable to all devices.
