Measurement points are given in Table 9.

a. Input pulse definition

Test data is given in Table 10.

Definitions test circuit:

RL = Load resistor.

CL = Load capacitance including jig and probe capacitance.

RT = Termination resistance should be equal to output impedance Zo of the pulse generator.

VEXT = Test voltage for switching times.
