description/ordering information
These octal buffers line drivers designed specifically improve performance density 3-state memory address drivers, clock drivers, bus-oriented receivers transmitters. 'AC240 devices organized 4-bit buffers/drivers with separate output-enable (OE) inputs. When low, device passes inverted data from inputs outputs. When high, outputs high-impedance state. ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver.

Stresses beyond those listed under "absolute maximum ratings" cause permanent damage device. These stress ratings only, functional operation device these other conditions beyond those indicated under "recommended operating conditions" implied. Exposure absolute-maximum-rated conditions extended periods affect device reliability. NOTES: input output voltage ratings exceeded input output current ratings observed. package thermal impedance calculated accordance with JESD 51-7.
