Note 8-7
This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down and pull-up
resistors add +/- 50uA per-pin (typical).
Note 8-8
This is the total 5.5V input leakage for the entire device.
Note 8-9
XI can optionally be driven from a 25MHz single-ended clock oscillator.
Note 8-10
Measured at line side of transformer, line replaced by 100
Ω (+/- 1%) resistor.
Note 8-11
Offset from 16nS pulse width at 50% of pulse peak.
Note 8-12
Measured differentially.
Note 8-13
Min/max voltages guaranteed as measured with 100
Ω resistive load.
