Quad 2-Input Multiplexer 3-State Output

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.
