description/ordering information

These octal buffers and line drivers are designed

specifically to improve the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and

transmitters.

The ’AC244 devices are organized as two 4-bit

buffers/drivers with separate output-enable (OE)

inputs. When OE is low, the device passes

noninverted data from the A inputs to the Y

outputs. When OE is high, the outputs are in the

high-impedance state.

SN54AC244 . . . FK PACKAGE

(TOP VIEW)

To ensure the high-impedance state during power

up or power down, OE should be tied to V

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.
