Note 1: All output leakage’s are measured with all 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: Contact SMSC for the latest values.
Note 4: Max ITRI with VCC = 3.3V (nominal) and CIR ‘on’ is 10 mA.
