description/ordering information  
This 16-bit buffer/driver is operational at 0.8-V to  
2.7-V V , but is designed specifically for 1.65-V  
CC  
to 1.95-V V  
operation.  
CC  
The SN74AUCH16244 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 V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
