description  
These octal buffers and line drivers are designed specifically for low-voltage (3.3-V) V operation, but with the  
CC  
capability to provide a TTL interface to a 5-V system environment.  
The ’LVT244 is 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.  
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 SN74LVT244 is packaged 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 SN54LVT244 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74LVT244 is characterized for operation from –40°C to 85°C.
