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.
