4 Description (continued)

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. TI does not recommend the use of pullup or pulldown resistors with bus-hold circuitry.

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.

The VCC isolation feature places the outputs in the high-impedance state if either VCCA or VCCB is at GND. The bus-hold circuitry on the powered-up side always stays active.

NanoFree package technology is a major breakthrough in IC packaging concepts, using the die as the package.
