3-State Outputs  
The TC74HC240A, 241A and 244A are high speed CMOS  
OCTAL BUS BUFFERs fabricated with silicon gate C2MOS  
technology.  
They achieve the high speed operation similar to equivalent  
LSTTL while maintaining the CMOS low power dissipation.  
The 74HC240A is an inverting 3-state buffer having two  
active-low output enables. The TC74HC241A and TC74HC244A  
are non-inverting 3-state buffers that differ only in that the 241A  
has one active-high and one active-low output enable, and the  
244A has two active-low output enables.  
TC74HC240AF, TC74HC241AF, TC74HC244AF  
These devices are designed to be used with 3-state memory  
address drivers, etc.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.
