The F541 octal buffer/line driver is ideal for driving  
bus lines or buffering memory address registers.  
The device features 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.
