Logic Design LAB 7

This lab focuses on implementing an 8-to-1 multiplexer using the LS74151 IC and other components such as LED, switch, and resistors. The lab also covers reducing logical equations and using K-maps to simplify the circuit. Learn how to convert Y to F and explore different reduction methods in this comprehensive lab.

  1. Logic Design LAB 7 授課老師：伍紹勳課程助教：邱麟凱、江長庭

  2. Multiplexer • Outline • Requirement • 8 to 1 multiplexer • LS74151 8 to 1 multiplexer • Lab

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

  4. 8 to 1 multiplexer

  5. LS74151 8 to 1 multiplexer

  6. Lab • Implement • How to convert Y to F ?

  7. Lab • Inspect equations and we can find that • 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

  8. Lab • Example • Reduce • And we can get

  9. Lab • Reduce again • And we can get

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