1. Input or I/O leakage current is measured with the pin congured as an input or as an I/O with the output driver tristated. It is not
measured with the output driver active. Bus maintenance circuits are disabled.
2. IIH excursions of up to 1.5A maximum per pin above the spec limit may be observed for certain voltage conditions on no more than 10% of
the device’s I/O pins.
3. Measured TA = 25°C, f = 1.0MHz.
