These octal buffers/drivers are designed for 2.7-V  
to 5.5-V V operation.

The ’LV240 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  
The ’LV240 are organized as two 4-bit buffers/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 SN74LV240 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 SN54LV240 is characterized for operation over the full military temperature range of −55°C to 125°C. The  
SN74LV240 is characterized for operation from −40°C to 85°C.
