DESCRIPTION/ORDERING INFORMATION  
This 16-bit buffer/driver is designed for 1.65-V to  
3.6-V VCC operation.  
The SN74ALVCH16244 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.  
To ensure the high-impedance state during power up  
or power down, OE should be tied to VCC through a  
pullup resistor; the minimum value of the resistor is  
determined by the current-sinking capability of the  
driver.
