NOTES: A. CL includes probe and test-fixture 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. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following
characteristics: PRR ≤ 1 MHz, ZO = 50 , tr = 6 ns, tf = 6 ns.
D. For clock inputs, fmax is measured when the input duty cycle is 50%.
E. The outputs are measured one at a time, with one input transition per measurement.
F. tPLZ and tPHZ are the same as tdis.
G. tPZL and tPZH are the same as ten.
H. tPLH and tPHL are the same as tpd.
