The device operates as a 10-bit bus switch or a 5-bit bus exchanger. The bus exchange BX signal provides nibble swapping of the AB and CD pairs of signals. This exchange configuration allows byte swapping of buses in systems. It can also be used as a quad 2-to-1 multiplexer and to create low delay barrel shifters.
