74AC16244 具有三态输出的 16 位缓冲器和线路驱动器
74AC16244 描述
The 'AC16244 are 16-bit buffers/line drivers designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. They can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable 
inputs. When 
is low, the device passes noninverted data from the A inputs to the Y outputs. When is high, the outputs are in the high-impedance state.
The 74AC16244 is packaged in the TI's shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area
