QUAD 2-INPUT MULTIPLEXER  
WITH 3-STATE OUTPUTS  
The LSTTL/MSI SN54/74LS257B and the SN54/74LS258B are Quad  
2-Input Multiplexers 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 (E ) In-  
O
LOW POWER SCHOTTKY  
put, allowing the outputs to interface directly with bus oriented systems. It is  
fabricated with the Schottky barrier diode process for high speed and is com-  
pletely compatible with all Motorola TTL families.
