Four bits of data from two sources can be selected using the common select input. The four buffered outputs present the selected data in the true (non-inverting) form. The FCT257T has a common Output Enable (OE) input. When OE is high,alloutputsareswitchedtoahigh-impedancestateallowingtheoutputs to interface directly with bus-oriented systems.
