description  
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  
(OE1 or OE2) input is high, all corresponding  
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 through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN54ABT540 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74ABT540 is characterized for operation from –40°C to 85°C.
