description/ordering information
These octal buffers/drivers designed specifically improve performance density 3-state memory-address drivers, clock drivers, bus-oriented receivers transmitters. 'AHC240 devices organized 4-bit buffers/line drivers with separate output-enable (OE) inputs. When low, device passes 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.
