Description : LOW VOLTAGE QUAD 2-INPUT MULTIPLEXER WITH 5V TOLERANT INPUTS AND OUTPUTS View

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 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.
