The SN74LVCH162244A is designed specifically to improve both the performance and density of 3-state memory

address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit

buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable

(OE) inputs.
