SN54ACT16244的产品描述：
The SN54ACT16244 and 74ACT16244 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. The devices provide true outputs and symmetrical OE (active-low) output-enable inputs.
The 74ACT16244 is packaged in TI!fls shrink small-outline package, which provides twice the I/O pin count an functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ACT16244 is characterized for operation over the full military temperature range of -55℃ to 125℃.The 74ACT16244 is characterized for operation from -40℃to 85℃.
