Integrated circuit symbols

About these integrated circuit symbols

The integrated circuit symbols in the form of chips are vital to the electronics industry. They combine several components into one. These include basic logic gates up to complex microcontrollers and processors.

That is why it is important to know IC symbols to be able to read schematics and implement the designs in the right manner. These symbols provide key information about the IC. They help engineers and technicians work effectively.

Logic gate IC

A logic gate IC is symbolized by a rectangle with specific gate symbols (AND, OR, NOT). These ICs are key in digital signal processing. They are needed for simple logical functions in computations and data flow control.

Operational amplifier

This IC symbol is a triangle with the input marked as '+' and '-' and an output line is also drawn. It increases voltage signals. It's widely used for signal conditioning, filtering, and instrumentation.

Microcontroller

A microcontroller symbol is a rectangle with its name (MCU). It has power pins, input/output pins, and communication interfaces. Many of these ICs combine a CPU, memory, and peripherals. So, they are now suitable for automation and control.

Timer IC

A timer IC like the 555 timer IC has a rectangular symbol with marked terminals like trigger, threshold, and output. It employs accurate time delay, pulse width modulation, or oscillation.

Voltage regulator

The voltage regulator IC symbol has a rectangle with the inputs, outputs, and ground pins indicated. Its main function is to maintain voltage steady.

Memory IC

The memory IC symbol is made of a rectangular shape having its type written on it, such as RAM or ROM. These ICs provide for storing and recalling data, which makes them central to computing and embedded systems.

Analog to digital converter (ADC)

Analog-to-digital converter symbol is a rectangle accompanied by the label. They sample an analog signal, like voltage or current. Then, they convert it to digital form for a microcontroller or computer to process.

Digital to Analog Conversion (DAC)

The DAC symbol comprises a rectangle with input in digital and output in analog form. It performs the reverse function of an ADC, turning digital signals into analog outputs.

Power amplifier

The power amplifier IC symbol is a triangle that contains a power and output pin indicated. Voltage amplifiers increase low voltage signals. These are needed to drive high-load equipment.

Multiplexer/Demultiplexer

The multiplexer symbol is symbolized by a rectangle that has more than one input/output/connection pin. These ICs provide optimal signal pathways to and between several channels.

Oscillator IC

The oscillator symbol is a rectangle with a 'sine wave AC' symbol within it. It provides the regular clock signals needed in the timing and synchronizing circuits.
