Four bits of data from two sources can be selected using a Common Data Select input.
The four outputs present the selected data in true (noninverted) form.
The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with busoriented systems.
Logic Symbols IEEE/IEC Figure 1.
