These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clockdrivers, and bus-oriented receivers and transmitters. The SNx4HCT244 devices are organized as two 4-bit buffers or drivers with separate 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.
