description/ordering information

18 1Y1

These octal buffers/drivers 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 ’AHCT244 devices 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.

SN54AHCT244 . . . FK PACKAGE

(TOP VIEW)

To ensure the high-impedance state during power

up or power down, OE should be tied to V

1 20 19

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.
