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