The TC74VHCT240A and 244A are advanced high speed  
CMOS OCTAL BUS BUFFERs fabricated with silicon gate  
2
C MOS technology. They achieve the high speed operation  
similar to equivalent Bipolar Schottky TTL while maintaining  
the CMOS low power dissipation.  
The TC74VHCT240A is an inverting 3-state buffer having two  
active-low output enables. The TC74VHCT244A 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.  
The input voltage are compatible with TTL output voltage.  
These devices may be used as a level converter for interfacing  
3.3 V to 5 V system.  
Input protection and output circuit ensure that 0 to 5.5 V can  
be applied to the input and output (Note) pins without regard to  
the supply voltage. These structure prevents device destruction  
due to mismatched supply and input/output voltages such as  
battery back up, hot board insertion, etc.
