Truth Table to Karnaugh Map Converter
Type a truth table's outputs directly and watch the corresponding Karnaugh map, minimized expression, and circuit build themselves automatically.
Why use this truth table to karnaugh map converter
No manual re-plotting
Skip manually figuring out which K-map cell each truth table row belongs to — it's handled automatically via Gray code ordering.
Good for checking homework
Enter a truth table from a textbook problem and immediately see the correct map and minimal expression.
Two-way sync
Switch to K-map view any time to see the same data laid out spatially, and back again without losing anything.
Frequently asked questions
How does a truth table map to K-map cells?
Each truth table row corresponds to exactly one K-map cell, positioned using Gray code ordering rather than plain binary row order, so adjacent map cells differ by only one input bit.
Can I mark a truth table row as don't-care?
Yes — clicking a row's output cycles through 0, 1, and X (don't-care).
Does row order in the truth table matter?
No — every row is labeled by its exact input combination, so it doesn't matter what order you fill them in.
