Description
General part information
74ABT540 Series
The ’ABT540 octal buffers and line drivers are ideal for driving bus lines or buffer memory address registers. The devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout.
The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1orOE2) input is high, all corresponding outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down,OEshould be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
