Multiplexer Outline Requirement 8 to 1 multiplexer LS74151 8 to 1 multiplexer Lab

Requirement IC:74151 x 1、7404 x 1、7408 x 2、LED x 1、Switch x 1、220Ω電阻 x 8

8 to 1 multiplexer

LS74151 8 to 1 multiplexer

Lab Implement How to convert Y to F ?

Lab Inspect equations and we can find that Draw K-map to reduce F! F has sum of 9 products Y has sum of 8 products Draw K-map to reduce F! If we reduce F to less or equal than 8 SOP, then we can use Y to represent F

Lab Example Reduce And we can get

Lab Reduce again And we can get

Lab Please use other reduce method to do this lab LS 74151
