description
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’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.
