描述 Description

The 'ABT16825 devices are 18-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 two 9-bit buffers or one 18-bit buffer. They provide true data. The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output-enable (OE1\\ or OE2\\) input is high, all nine affected outputs are in the high-impedance state. When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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.
