description

These octal buffers/line drivers are designed for

The ’LV244 are designed specifically to improve

both the performance and density of 3-state

memory address drivers, clock drivers, and

bus-oriented receivers and transmitters.

The ’LV244 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.

The SN74LV244 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 SN54LV244 is characterized for operation over the full military temperature range of −55

°C to 125°C. The

SN74LV244 is characterized for operation from −40

°C to 85°C.
