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 the common Output Enable (OE#) input, allowing the outputs to interface directly with bus-oriented systems. The 74LCX257 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
