Parameter Measurement Information (Continued)

Note 9: The input pulse is supplied by a generator having the following characteristics: PRR = 1.0 MHz, 50% duty cycle, tr ≤ 6.0 ns, tf ≤ 6.0 ns, ZO =50Ω.

Note 10: CL includes probe and stray capacitance.

Note 11: DS96173 with active high and active low Enables is shown here. DS96175 has active high Enable only.

Note 12: All diodes are 1N916 or equivalent.

Note 13: To test the active low Enable E of DS96173, ground E and apply an inverted input waveform to E . DS96175 has active high Enable only.
