CL 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 condition such that the output is high except when disabled by the output control. C. C. All input pulses have the following characteristics: PRR ≤ 1 MHz, tr = tf = 2 ns, duty cycle = 50% D. The outputs are measured one at a time with one transition per measurement. Figure 1 |
