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 (OE
) 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.
