DESCRIPTION  
The M54/74HC7240, HC7241andHC7244 are high  
speed CMOS OCTAL BUS BUFFERs fabricated in  
silicon gate C2MOS technology.  
governs four BUS BUFFERs.  
The HC7240, HC7241 and HC7244 have the same  
pin configuration andfunctionas the HC240, HC241  
They have the same high speed performance of  
LSTTL combined with true CMOS low power  
consumption.  
and HC244 and they have  
characteristics with each input so can be used as a  
line receiver, etc.
