Parameter Measurement Information
Notes:
• C
• Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
• All input pulses are supplied by generators having the following characteristics: PRR ≤ 10Mz, Z
• The outputs are measured one at a time with one transition per measurement.
• t
