MICROCIRCUIT DATA SHEET Original Creation Date: 06/25/97 Last Update Date: 07/08/97 Last Major Revision Date: 06/25/97 CN54F257A-X REV 0A0 QUAD 2-INPUT MULTIPLEXER WITH TRI-STATE OUTPUTS General Description The F257A is a quad 2-Input multiplexer with Tri-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 with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
