description

The 'AC16240 are 16-bit buffers and 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 inverting outputs and symmetrical active-low output-enable inputs.

The 74AC16240 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 54AC16240 is characterized for operation over the full military temperature range of -55°C to 125°C.

The 74AC16240 is characterized for operation from -40°C to 85°C.
