Note 1: All output leakage’s are measured with the current pins in high impedance.

Note 2: Output leakage is measured with the low driving output off, either for a high level output or a

high impedance state.

Note 3: KBCLK, KBDATA, MCLK, MDATA contain 90uA min pull-ups.

Note 4: Please contact SMSC for the latest value.
