16-Bit Buffers/Drivers With 3-State Outputs

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.
