DESCRIPTION/ORDERING INFORMATION (CONTINUED)
This device can be used as eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. The
device provides true outputs and has symmetrical active-output-enable (OE) inputs. It is designed specifically to
improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented
receivers and transmitters.

3.3-V ABT 32-BIT BUFFER/DRIVER
WITH 3-STATE OUTPUTS
SCBS748C–OCTOBER 2000–REVISED NOVEMBER 2006
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.
This device is fully specified for hot-insertion applications using I
off
and power-up 3-state. The I
off
circuitry
disables the outputs, preventing damaging current backflow through the device when it is powered down. The
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,
which prevents driver conflict.
