SN74AVC2T45: SN74AVC2T45

Part Number: SN74AVC2T45

Hello,

What is the state of I/O of this device when there is no power for both the supplies VCCA and VCCB. Will the device allow any leakage path?

Thanks
Kamesh.

Hi Kamesh,

The AVC2T45 supports Ioff partial power down mode or Vcc isolation, wherein the IO ports are in Hi-z when either one or both supplies are held at 0V.

The electrial spec in the datasheet lists the Ioff leakage current numbers.

Hi Shreyas,

The datasheet mentioned about either or only. Are you sure that when both the supplies are not there , the I/O's will be in high impedance state

Thanks

Hi Kamesh,

Either one or both supplies powered down ensures Ioff Vcc isolation.
