DESCRIPTION/ORDERING INFORMATION  
This 32-bit buffer/driver is designed for 2.7-V to 3.6-V VCC operation.  
The SN74LVCZ32244A is designed specifically to improve the performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented receivers and transmitters.  
The device can be used as eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. It  
provides true outputs.
