SN74HC244

八路缓冲器并用3态输出线路驱动器 OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS

The SNx4HC244 octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SNx4HC244 devices are organized as two 4-bit buffers and 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.
