µA Note 3, 4
µA Chip in circuit:
VCC = 0V
VIN = 6V Max.
Note 1: All output leakages are measured with the current pins in high impedance as defined by the PWRGD pin.
Note 2: Output leakage is measured with the low driving output off, either for a high level output or a high impedance
state defined by PWRGD.
Note 3: Defined by the device configuration with the PWRGD input low and 14 MHz clock inactive.
Note 4: Max standby supply current given is for Rev. H and K parts. Contact SMSC for Rev. J and all other Revs.
