SCES551E – FEBRUARY 2004 – REVISED NOVEMBER 2015

5 Description (continued)

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.

To ensure the high-impedance state during power up or power down, OE should be tied to VCCA through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
