description  
These octal buffers and line drivers are designed  
to have the performance of the popular  
SN54ALS240A/SN74ALS240A series and, at  
the same time, offer a pinout with inputs and  
outputs on opposite sides of the package. This  
arrangement greatly facilitates printed circuit  
board layout.  
GND  
The 3-state control gate is a 2-input NOR gate  
such that, if either output-enable (OE1 or OE2)  
input is high, all eight outputs are in the  
high-impedance state.

(TOP VIEW)  
The SN74ALS540 provides inverted data. The  
’ALS541 provide true data at the outputs.
