description/ordering information
The ’ABT162244 devices are 16-bit buffers and
line drivers designed specifically to improve both
the performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented
receivers and transmitters. These devices can be
used as four 4-bit buffers, two 8-bit buffers, or one
16-bit buffer. These devices provide noninverting
outputs and symmetrical active-low
output-enable (OE) inputs.

The outputs, which are designed to source or sink up to 12 mA, include equivalent 25-Ω series resistors to
reduce overshoot and undershoot.
To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
