产品概述
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- series resistors to
reduce overshoot and undershoot.To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the devices when they are 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.
