NOTES:

1. Over recommended free-air operating temperature range and supply voltage range unless otherwise specified. For conditions shown as MIN

or MAX, use the appropriate value specified under recommended operating conditions.

2. All voltages measurements are referenced to ground. All time measurements are at the 50% level for inputs (except tBRH and tBRL) and at

0.8V and 2.0V for outputs. Input levels swing between 0.4V and 2.4V, with a transition time of ≤ 20ns maximum.

3. Typical values are at +25°C, typical supply voltages and typical processing parameters.

4. INTR, TxRDY, RxRDY and TxEMT/DSCHG outputs are open-drain.

CAPACITANCE TA = 25°C, VCC = 0V
