What operators does this truth table generator support?

This generator supports AND (&&, &, ∧), OR (||, |, ∨), NOT (!, ~, ¬), XOR (^, ⊕), NAND, NOR, XNOR (⊙), IMPLIES (→, =>), and BICONDITIONAL (↔, ). You can use parentheses for grouping.

How many variables can I use in a truth table?

This tool supports up to 8 variables (A through H). The number of rows doubles with each variable: 2 variables produce 4 rows, 3 variables produce 8 rows, and 8 variables produce 256 rows.

What is the difference between XOR and XNOR?

XOR (exclusive OR) returns true when exactly one of the inputs is true. XNOR (exclusive NOR) is the negation of XOR — it returns true when both inputs are the same (both true or both false). XNOR is also called the biconditional or equivalence operator.

What Is a Truth Table?

A truth table is a systematic way to list all possible truth values of a logical expression. For each combination of input variable values (True or False), the table shows the resulting output of the expression. Truth tables are fundamental in:

Digital Logic Design — designing circuits with AND, OR, NOT gates
Computer Science — evaluating conditional expressions and boolean algebra
Philosophy & Mathematics — formal proofs in propositional logic
Software Engineering — testing all branches of conditional logic

At a Glance

Truth Table Generator builds a Boolean truth table from an expression using up to eight variables, A through H. It supports AND, OR, NOT, XOR, NAND, NOR, XNOR, implication and biconditional operators.

Truth Table Generator: features at a glance
Feature	What you get	Good for
Variables	Use single uppercase letters A to H, up to 8 variables. The tool detects the variables in your expression and lists every True and False combination.	Checking all cases of a logic expression
Operators	NOT, AND, NAND, XOR, XNOR, OR, NOR, IMPLIES and biconditional, typed as symbols such as !, &&, ^, ->, => and <=>, or with the operator buttons.	Writing expressions in the notation you already use
Precedence	Operators are evaluated from NOT (highest) down to biconditional (lowest), and parentheses override the order.	Avoiding mistakes in long expressions
Sub-expressions	A toggle shows the intermediate results of each part of the expression.	Following how the final column is built
Minterms and maxterms	Rows with output 1 give the Sum of Minterms and rows with output 0 give the Product of Maxterms.	Digital logic simplification and Karnaugh map work

How to Use This Truth Table Generator

Enter a boolean expression using variables (A-H) and logical operators. The tool will automatically detect your variables and generate the complete truth table showing all possible input/output combinations.

Use single uppercase letters (A, B, C, ..., H) as variables — up to 8 variables supported
Use parentheses ( ) to control operator precedence
Click the operator buttons or type operators directly
Toggle "Show Sub-expressions" to see intermediate calculation steps

Operator Precedence (Highest to Lowest)

When no parentheses are used, operators are evaluated in this order:

NOT (!, ~, ¬) — evaluated first (highest precedence)
AND (&&, &, ∧) — evaluated second
NAND — evaluated third
XOR, XNOR (^, ⊕, ⊙) — evaluated fourth
OR (||, |, ∨) — evaluated fifth
NOR — evaluated sixth
IMPLIES (→, =>) — evaluated seventh
BICONDITIONAL / IFF (↔, <=>) — evaluated last (lowest precedence)

Supported Operator Syntax

Truth Table Generator: Supported Operator Syntax
Operator	Accepted Syntax	Description	Example
AND	AND, &&, &, ∧, ·	True only when both operands are true	`A AND B`
OR	OR, \|\|, \|, ∨, +	True when at least one operand is true	`A OR B`
NOT	NOT, !, ~, ¬	Inverts the truth value	`NOT A`
XOR	XOR, ^, ⊕	True when operands differ	`A XOR B`
NAND	NAND	Negation of AND	`A NAND B`
NOR	NOR	Negation of OR	`A NOR B`
XNOR	XNOR, ⊙	True when operands are the same	`A XNOR B`
IMPLIES	→, =>, IMPLIES	False only when P is true and Q is false	`A → B`
BICONDITIONAL	↔, <=>, IFF	True when both have the same value	`A ↔ B`

Understanding Minterms and Maxterms

Minterms are the rows where the output is 1 (True). The Sum of Minterms (SOP) expresses the function as an OR of AND terms. Maxterms are the rows where the output is 0 (False). The Product of Maxterms (POS) expresses the function as an AND of OR terms. Both forms are essential in digital logic simplification and Karnaugh map analysis.
