Non-Inverted, 3-State Outputs  
The TC74VHC240 and 244 are advanced high speed CMOS  
OCTAL BUS BUFFERs fabricated with silicon gate C2MOS  
technology.  
They achieve the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
The 74VHC240 is an inverting 3-state buffer having two  
active-low output enables. The TC74VHC244 is a non-inverting  
3-state buffer, and has two active-low output enables.  
These devices are designed to be used with 3-state memory  
address drivers, etc.  
An input protection circuit ensures that 0 to 5.5 V can be  
applied to the input pins without regard to the supply voltage.  
This device can be used to interface 5 V to 3 V systems and two  
supply systems such as battery back up. This circuit prevents  
device destruction due to mismatched supply and input voltages.
