description  
The SN54ABT541 and SN74ABT541B 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 two-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.  
When V  
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT541 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT541B is characterized for operation from –40°C to 85°C.
