Tabel kebenaran

IEC 60617-12

US-Norm

DIN 40700 (sebelum 1976)

Gerbang-AND
(AND)

$Y = A \wedge B$

$Y = A\cdot B$

$Y = A\,B$

Gerbang-OR
(OR)

$Y = A \vee B$

$Y = A + B\!$

Gerbang-NOT
(NOT, Gerbang-komplemen, Pembalik(Inverter))

$Y = \overline{A}$

$Y = \neg A$

A	Y
0	1
1	0

Gerbang-NAND
(Not-AND)

$Y = \overline{A \wedge B}$

$Y = A \overline{\wedge} B$

$Y = \overline{A\,B}$

Gerbang-NOR
(Not-OR)

$Y = \overline{A \vee B}$

$Y = A \overline{\vee} B$

$Y = \overline{A + B}$

Gerbang-XOR
(Antivalen, Exclusive-OR)

$Y = A \,\underline{\lor}\, B$

$Y = A \oplus B$

atau

Gerbang-XNOR
(Ekuivalen, Not-Exclusive-OR)

$Y = \overline{A \,\underline{\lor}\, B}$

$Y = A \,\overline{\underline{\lor}}\, B$

$Y = \overline{A \oplus B}$

atau
