NOT gate symbol

About the NOT gate symbol

NOT gate or inverter is one of the simplest basic modules of digital circuits. The invert is a basic gate that performs solely on the operational input of a single binary input. Its main application is negating or inverting the operated signal.

A NOT gate symbol is represented by a triangle and a small circle facing it. The triangle represents the processing action and the circle at the output represents inversion; its unique design visually represents its primary purpose: flipping the binary state.

The NOT gate symbol also has one input and one output only. If the input is HIGH (1), it inverts it and gives output LOW (0) and vice versa. Its negation function makes it vital for many digital circuits and is commonly employed in digital systems to provide an inversion of signals.

NOT gates are also important when used together with other gates like NAND, NOR and XOR are vital in the formation of more complicated operations. In the delay or clock circuits, NOT gates assist in the altering of signal characteristics. They are used in creating feedback paths in latches and flip flops which are basic structures of memory devices.

NOT gate

The NOT gate symbol is a triangle with another small circle beside the output. This operates on one input and, to change the logic of its input, it outputs HIGH in the case of LOW input and vice versa. This symbol is very frequently used in digital signal diagrams since its negation property is highly valuable.

NAND gate

The NAND gate symbol is the symbol of the AND gate which has an inverted bubble (Not gate) on the output. With all the inputs being HIGH its output would be LOW. NAND gates are preferred more in digital electronics due to their characteristic of being able to perform as any type of gate.

NOR gate

The symbol for the NOR gate is similar to that of an OR gate only with a NOT gate at output. It produces HIGH only when all the inputs are in the LOW state and it finds usage where logic minimization is desired.

XNOR gate

The symbol for the XNOR gate is similar to that of the XOR gate symbol modified by a NOT gate at the output end, to represent negation. If its inputs are HIGH, it outputs HIGH and is used particularly for parity checking and error detection.

Flip-Flop

Flop flops are crucial components of memories in a digital circuit. They store one bit of data. They are made from basic logic gates, as are the NOT gate symbols in feedback.
