QUAD 2-INPUT MULTIPLEXER  
WITH 3-STATE OUTPUTS  
The MC74F257 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 with a HIGH on the com-  
mon Output Enable (OE) input, allowing the outputs to interface directly with  
bus oriented systems.
