OCTAL BUFFER/DRIVER

WITH 3-STATE OUTPUTS

SCES573A – JUNE 2004 – REVISED AUGUST 2005

This device is ideal for driving bus lines or buffer memory address registers. It features inputs and outputs on

opposite sides of the package to facilitate printed circuit board layout.

The 3-state control gate is a two-input AND gate with active-low inputs so that, if either output-enable (OE1 or

OE2) input is high, all corresponding outputs are in the high-impedance state. The outputs provide noninverted

data when they are not in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE shall be tied to VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

preventing damaging current backflow through the device when it is powered down.
