MC74AC257, MC74ACT257 Quad 2-Input Multiplexer with 3-State Outputs The MC74AC257/74ACT257 is a quad 2−input multiplexer with 3−state outputs. 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 bus−oriented systems. • Multiplexe.
