The TC74LVX240,244F/ FT is a high-speed CMOS OCTAL  
BUS BUFFER fabricated using silicon gate CMOS technology.  
Designed for use in 3-V systems, it achieves high-speed operation  
while maintaining the CMOS low power dissipation. This device  
is suitable for low-voltage and battery operated systems.  
The TC74LVX240 is an inverting 3-state buffer while the  
TC74LVX244 is non-inverting. Both devices have two active-low  
output enables. These devices are designed to be used in such  
applications as 3-state memory address drivers.  
TC74LVX240FT, TC74LVX244FT  
An input protection circuit ensures that 0 to 5.5V can be  
applied to the input pins without regard to the supply voltage.  
This device can be used to interface 5V to 3V systems and two  
supply systems such as battery back up. This circuit prevents  
device destruction due to mismatched supply and input voltages.
