description
The 74AC11244 is an octal buffer or line driver designed specifically to improve both the performance and
density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The
device can be used as two 4-bit buffers or one 8-bit buffer, with active-low 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.
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 74AC11244 is characterized for operation from –40°C to 85°C.

‡
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.
