(1) All control inputs are TTL levels.
NOTES: A. CL includes probe and jig capacitance.
B. All input pulses are supplied by generators having the following characteristics: PRR
≤ 10 MHz, ZO = 50 , tr ≤ 2.5 ns, tf ≤ 2.5 ns.
C. 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.
D. The outputs are measured one at a time, with one transition per measurement.
