The IMPLY gate is a digital logic gate that implements a logical conditional pictured with a right-facing arrow ( $\rightarrow$ ).

F=A'+B ( Implication)

[If A is true output follows B otherwise output is always true.

Symbols

There are two symbols for IMPLY gates: the traditional symbol and the IEEE symbol. For more information see Logic gate symbols.


Traditional IMPLY Symbol		IEEE IMPLY Symbol

The logic symbol → can be used to denote IMPLY in algebraic expressions.

v t e Logical connectives
Tautology/True $\top$
Alternative denial (NAND gate) $\uparrow$ Converse implication $\leftarrow$ Implication (IMPLY gate) $\rightarrow$ Disjunction (OR gate) $\lor$
Negation (NOT gate) $\neg$ Exclusive or (XOR gate) $\not \leftrightarrow$ Biconditional (XNOR gate) $\leftrightarrow$ Statement (Digital buffer)
Joint denial (NOR gate) $\downarrow$ Nonimplication (NIMPLY gate) $\nrightarrow$ Converse nonimplication $\nleftarrow$ Conjunction (AND gate) $\land$
Contradiction/False $\bot$
