description  
These octal buffers and line drivers are designed  
specifically for low-voltage (3.3-V) V operation,  
9 10 11 12 13  
CC  
but with the capability to provide a TTL interface to  
a 5-V system environment.  
The ’LVTT240 is organized as two 4-bit buffer/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  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
through a pullup  
CC  
The SN74LVTT240 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 SN54LVTT240 is characterized for operation over the full military temperature range of −55°C to 125°C.  
The SN74LVTT240 is characterized for operation from −40°C to 85°C.
