74LCX257 Low Voltage Quad 2-Input Multiplexer with 5V Tolerant Inputs and Outputs May 1995 Revised September 2000 Low Voltage Quad 2-Input Multiplexer with 5V Tolerant Inputs and Outputs General Description The LCX257 is a quad 2-input multiplexer with 3-STATE outputs. Four bits of data from two sources can be selected using a mon 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 mon Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. The 74LCX257 is fabricated with advanced CMOS technology to achieve...
