The SN54BCT540 and SN74BCT540A 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 to facilitate printed circuit board layout.\n\n 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 corresponding outputs are in the high-impedance state.\n\n 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.
