description/ordering information  
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVCH162244A is designed specifically to improve both 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.
