description  
These octal buffers/drivers are designed  
specifically for low-voltage (3.3-V) V operation  
9 10 11 12 13  
CC  
with the capability to provide a TTL interface to a  
5-V system environment.  
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.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74LVTZ244 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count  
and functionality of standard small-outline packages in less than half the printed-circuit-board area.  
The SN54LVTZ244 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LVTZ244 is characterized for operation from –40°C to 85°C.
