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 (active-low) output-enable inputs.
The 74ACT16244 is packaged in 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.
The SN54ACT16244 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16244 is characterized for operation from -40°C to 85°C.
