Notes
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Above 110 °C the value of PD derates linearly with 8 mW/K.

Definitions for test circuit:
CL = load capacitance including jig and probe capacitance (see “AC characteristics”).
RL = Load resistance.
RT = termination resistance should be equal to the output impedance Zo of the pulse generator.
