description  
GND 10  
These octal buffers and line drivers are designed  
to have the performance of the popular ’HC240  
series and to offer 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  
’HCT541 provide true data at the outputs.
