description/ordering information (continued)

The SN74LVC2T45 is designed so that the DIR input circuit is supplied by VCCA.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.

The VCC isolation feature ensures that if either VCC input is at GND, both ports are in the high-impedance state.

NanoStar

 and NanoFree package technology is a major breakthrough in IC packaging concepts, using the

die as the package.
