description
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 (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.
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.
The 54AC16244 is characterized for operation over the full military temperature range of –55°C to 125°C. The
74AC16244 is characterized for operation from –40°C to 85°C.
