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 () 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.
