ISO7740-Q1 ISO7741-Q1 ISO7742-Q1 Switching Characteristics Test Circuit and Voltage Waveforms
A. The input pulse is supplied by a generator having the following characteristics: PRR ≤ 50kHz, 50% duty cycle, tr ≤ 3ns, tf ≤ 3ns, ZO = 50Ω. At the input, 50Ω resistor is required to terminate Input Generator signal. The 50Ω resistor is not needed in actual application.
B. CL = 15pF and includes instrumentation and fixture capacitance within ±20%.
