Note 7-5

This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down and pull-up

resistors add +/- 50 µA per-pin (typical).

Note 7-6

XI can optionally be driven from a 25 MHz single-ended clock oscillator.

Note 7-7

Measured at line side of transformer, line replaced by 100 Ω (+/-1%) resistor.

Note 7-8

Offset from 16 ns pulse width at 50% of pulse peak.

Note 7-9

Measured differentially.

Note 7-10

Min/max. voltages guaranteed as measured with 100 Ω resistive load.
