DESCRIPTION/ORDERING INFORMATION  
This 16-bit buffer/driver is designed for 1.65-V to  
3.6-V VCC operation.  
The SN74LVC16244A 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 four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and  
symmetrical active-low output-enable (OE) inputs.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in  
a mixed 3.3-V/5-V system environment.
