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.
