description
These octal buffers/line drivers are designed for
2-V to 5.5-V V
CC
operation.
The ’LV244A devices are designed specifically to
improve both the performance and density of
3-state memory address drivers, clock drivers,
and bus-oriented receivers and transmitters.
These devices 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.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54LV244A is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74LV244A is characterized for operation from –40
