description  
GND 10  
These octal buffers and line drivers are designed  
to have the performance of the ’HCT240 and a  
pinout with inputs and outputs on opposite sides  
of the package. This arrangement greatly  
facilitates printed circuit board layout.

The 3-state control gate is a 2-input NOR. If either  
output-enable (OE1 or OE2) input is high, all eight  
outputs are in the high-impedance state. The  
’HCT540 provide inverted data at the outputs.
