74LCX257 Low-Voltage Quad 2-Input Multiplexer

The LCX257 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 (non inverted) form. The outputs may be switched to a high impedance state by placing a logic HIGH on.
