description

These 16-bit buffers/bus drivers provide a high-performance bus interface for wide data paths.

The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (or) input is high, all corresponding outputs are in the high-impedance state.

The 74ACT16540 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 54ACT16540 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16540 is characterized for operation from -40°C to 85°C.
