NOTES: 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.
D. The outputs are measured one at a time, with one transition per measurement.
E. Since this device has open-drain outputs, t_PLZ and t_PZL are the same as t_pd.
F. t_PZL is measured at V_M.
G. t_PLZ is measured at V_OL + V_∆.
H. All parameters and waveforms are not applicable to all devices.
