DESCRIPTION/ORDERING INFORMATION (CONTINUED)
These devices are fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the
outputs, preventing damaging current backflow through the devices when they are powered down.

SCAS296N–JANUARY 1993–REVISED MAY 2005
To ensure the high-impedance state during power up or power down, OE should be tied to V
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
