Note 7.10 Measured differentially.
Measured at the line side of the transformer, line replaced by 100Ω (+/- 1%) resistor.
This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down
and pull-up resistors add +/- 50uA per-pin (typical).
This is the total V
the number of pins driven to V
are driven to the maximum operational limit for V
by the maximum input leakage current.
Measured at the line side of the transformer, line replaced by 100Ω (+/- 1%) resistor.
Offset from16 nS pulse width at 50% of pulse peak
