description/ordering information  
The SN74AHC541 octal buffer/driver is ideal for  
driving bus lines or buffer memory address  
registers. This device features inputs and outputs  
on opposite sides of the package to facilitate  
printed circuit board layout.  
GND  
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 should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
