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 VCC 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.
