description/ordering information
The SN54BCT541 and SN74BCT541A octal buffers and line drivers are ideal for driving bus lines or buffering
memory-address registers. The devices feature inputs and outputs on opposite sides of the package to 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 (OE1 or OE2)
input is high, all eight outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
