GERBANG LOGIKA DASAR

Tabel Kebenaran
gerbang NANDGerbang Logika => blok dasar untuk membentuk rangkaian elektronika digital
-->

·         Sebuah gerbang logika mempunyaisatu terminal output dan satu atau lebih terminal  input

·         Output-outputnya bisa bernilaiHIGH (1) atau LOW (0) tergantung dari level-level digital pada terminal inputnya.

·         Ada 7 gerbang logika dasar : AND, OR, NOT, NAND, NOR, Ex-OR, Ex-NOR

 

1. GerbangAND

 

Simbol gerbanglogika AND

--> -->

Operasi AND :

• Jika Input A AND B keduanya HIGH, maka output X akan HIGH

• Jika Input A atau B  salah satu atau keduanya LOW maka output X akan LOW

2. GerbangOR

Simbol gerbanglogika OR

Operasi OR : • J ika Input A OR B atau keduanya HIGH, maka output X akan HIGH • J ika Input A dan B  keduanya LOWmaka output X akan LOW

3. GerbangNOT / INVERTER

 

Simbol gerbanglogika NOT

Operasi NOT :

• J ika Input A  HIGH, maka output X akan LOW
• J ika Input A  LOW, maka output X akan HIGH

4. GerbangNAND

atau 

Simbol gerbanglogika NAND

Operasi NAND :
• Merupakan Inversi (kebalikan) dari operasi AND
• J ika Input A AND B keduanya HIGH, maka output X akan LOW
• J ika Input A atau B atau keduanya LOW, maka output X akan HIGH
