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 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.
