Non-Inverted, 3-State  
Outputs  
The TC74AC240 and 244 are advanced high speed CMOS  
OCTAL BUS BUFFERs fabricated with silicon gate and  
double-layer metal wiring C2MOS technology.  
They achieve the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
The 74AC240 is an inverting 3-state buffer while the 74AC244  
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.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.
