74LVC244A  
OCTAL BUFFER/LINE DRIVER WITH 3 STATE OUTPUTS  
Description  
Pin Assignments  
The 74LVC244A provides 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.  
The device is designed for operation with a power supply range of  
1.65V to 3.6V.  
The inputs are tolerant to 5.5V allowing this device to be used in a  
mixed voltage environment. The device is fully specified for partial  
power down applications using IOFF. The IOFF circuitry disables the  
output preventing damaging current backflow when the device is  
powered down.
