These octal buffers/line drivers are designed for  
2-V to 5.5-V V operation.

The ’LV244A devices are designed specifically to  
improve both the performance and density of  
3-state memory address drivers, clock drivers,  
and bus-oriented receivers and transmitters.  
9 10 11 12 13  
These devices are organized as two 4-bit line  
drivers with separate output-enable (OE) inputs.  
When OE is low, the device passes data from the  
A inputs to the Y outputs. When OE is high, the  
outputs are in the high-impedance state.  
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 SN54LV244A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LV244A is characterized for operation from –40°C to 85°C.
