Parameter Measurement Information
Note 9: The input pulse is supplied by a generator having the following characteristics: PRR = 1.0 MHz, 50% duty cycle, t
Note 10: C
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.
Typical Application
Note: The line length should be terminated at both ends in its characteristic impedance. Stub lengths off the main line should be kept as short as possible.
L
includes probe and stray capacitance.
