    Hi, I came across this strange symbol Strange.PNG
    It's in the Atmega328p datasheet, Ports as General Digital I/O, Figure 14.2
    Part of the circuit: part_of_circuit.PNG

    I've been searching for it for an hour. But got no result.

    Welcome aboard EP.

    The symbol stands for a transmission gate, an analog switch made from an NMOS/PMOS transistor pair.
