QUAD 2-INPUT  
MULTIPLEXER  
The MC74AC157/74ACT157 is a high-speed quad 2-input multiplexer. Four  
bits of data from two sources can be selected using the common Select and Enable  
inputs. The four outputs present the selected data in the true (noninverted) form.  
The MC74AC157/74ACT157 can also be used as a function generator.  
Outputs Source/Sink 24 mA
