Get Or Gate Schematic Symbol PNG. The truth table of the or gate along with its schematics symbol is shown below: The output state of a digital logic and gate only returns low again when any of its inputs are at a logic level 0.
In this schematic, two npn transistors are connected in parallel with each other.
American national standards institute (ansi) and the international electrotechnical commission (iec). Polygons are the symbols for the choosing gates: Or gate implements the or boolean function and similarly and and nor gates implements the or and nor functions respectively. In the logic symbols, the bubble represents the inversion.
