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
