includes probe and stray capacitance.
Note 12: DS96F173 with active high and active low Enables are shown. DS96F175 has active high Enable only.
Note 13: All diodes are 1N916 or equivalent.
Note 14: To test the active low Enable E of DS96F173, ground E and apply an inverted input waveform to E . DS96F175 has active high enable only.
Note 15: Testing at 20 pF assures conformance to 5 pF specification.
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.
