Multiplexer with CMOS IC 4556

Sunday, May 15, 2011 by skemarangkaian

In addition to the family of TTL ICs that support the function of a multiplexer is a family of CMOS ICs.

Despite the fact it is the family of TTL ICs that support more functions than the CMOS multiplexer. For the working principle of the multiplexer IC CMOS family is actually tantamount to a multiplexer circuit, or IC TTL logic gates. That should be all referring to the real multiplexer function, namely the determination of output lines which represent the number of input lines. The use of symbols is possible between TTL and CMOS IC has a different but actually run the same rules. For your reference if you are interested in using family of CMOS IC 4556 series in particular, I include also the truth table below:
