The ’AHCT540 octal buffers/drivers are ideal for  
driving bus lines or buffer memory address registers.  
These devices feature inputs and outputs on opposite  
sides of the package to facilitate printed circuit board  
layout.

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  
inverted 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 VCC through a  
pullup resistor; the minimum value of the resistor is  
determined by the current-sinking capability of the  
driver.
