DATASHEET
Note 4.6 This is the total 5.5V input leakage for the entire device.
Note 4.7 XI can optionally be driven from a 25MHz single-ended clock oscillator.
Note 4.8 Measured at line side of transformer, line replaced by 100Ω (+/- 1%) resistor.
Note 4.9 Offset from 16nS pulse width at 50% of pulse peak.
Note 4.10 Measured differentially.
Note 4.11 Min/max voltages guaranteed as measured with 100Ω resistive load.
