八路缓冲器和线路驱动器,具有三态输出 OCTAL BUFFER AND LINE DRIVER WITH 3-STATE OUTPUTS
These 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 HC244 are organized as two 4-bit buffers/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.
