Note 1: Output leakage is 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: Please contact SMSC for the latest values.
Note 4: The minimum values given for VTR is for VCC active. When VCC=0, the minimum value given for
VTR is 0V.
