description
The SN54ACT16240 and 74ACT16240 are 16-bit
buffers or 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. The
devices 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 74ACT16240 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 SN54ACT16240 is characterized for operation over the full military temperature range of –55°C to 125°C.
The 74ACT16240 is characterized for operation from –40°C to 85°C.
