HD74LS257  
Quadruple 2-line-to-1-line Data Selectors / Multiplexers  
(with not inverted 3-state outputs)  
REJ03D0469–0300  
Rev.3.00  
Jul.15.2005  
This multiplexer features three-state outputs that can interface directly with and drive data lines of bus-organized  
systems. With all but one of the common outputs disabled (at a high-impedance state) the low impedance of the single  
enabled output will drive the bus line to a high or low logic level.  
To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels, the output-  
enable circuitry is designed such that the output disable times are shorter than the output enable times.
