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 () inputs.

When is low, the device passes noninverted data from the A inputs to the Y outputs. When is high, the outputs are in the high-impedance state.

The 74AC11244 is characterized for operation from -40°C to 85°C.
