description  
The ’AHC16244 devices are 16-bit buffers and  
line drivers designed specifically to improve the  
performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented  
receivers and transmitters.  
4OE  
These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. They provide 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.  
The SN54AHC16244 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHC16244 is characterized for operation from –40°C to 85°C.
