74F257A  
Quad 2-Input Multiplexer with 3-STATE Outputs  
General Description  
Features  
The 74F257A 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 common Output Enable (OE) input, allowing  
the outputs to interface directly with bus-oriented systems.  
Multiplexer expansion by tying outputs together  
Non-inverting 3-STATE outputs  
Input clamp diodes limit high-speed termination effects
