What is a digital integrated circuit?

Digital integrated circuit (IC) is a highly miniaturized electronic circuit that works at each voltage level mounted in a small package. It usually works with a power supply with low -current low voltage (DC). Typical supply voltages are 5 and 3.3 volts (V). Earlier digital integrated circuits operated on 12 V sources.

different types of semiconductors, resistors and capacitors are used in a digital integrated circuit. The simplest digital integrated circuit could be a 14-round dual chip or a microchip that has six built-in digital inverters. Each inverter uses one pin and one pin for output. The inverter emits "high" when "low" is fed to the entrance, but when "high" is fed to the input, the output is "low". Therefore, it is called an inverter.

In electronics, computers, mobile phones and digital devices, there are so many types of digital integrated circuits that perform all types of functions including mathematicalÉ calculations using a system of binary numbers. In an 8 -bit microcomputer, a set of 8 bits is referred to as byte. Each byte can represent a number from 0 to 255, or it can represent –128 to +127. In certain calculation modes known as the binary coded decimal number, the byte can be a number from 00 to 99.

There are analog integrated circuits that perform various analog functions such as amplification, signal conversions and detection. The digital integrated circuit that works on digital levels can distinguish the digital equivalent of analog signals using a converter. An analog to digital (A/D) converter is a combined analog and digital circuit that enters an analog level and issues a multi -bit digital equivalent of analog sample. For example, the A/D converter can taste the voltage with a direct current of 24 volts (VDC) and generate a byte with the "00011000" bit values, what is "24."

digital converter to analog (D/A) is a simpler circuit that may not require an integrated circuit. The D/A converter can be created using passive devices such as resistors and analog amplifier. If the space is minimal, the D/A chip can be a practical choice.

In digital electronics, many circuits and devices are used. The microprocessor uses registers, which are sets of digital latches that retain one bit. The 16 -bit processor uses 16 of these latches that are able to remember only 1 bit. For memory applications, the density of semiconductors in the memory chips increased to contain more than a few dozen gigabytes per square inch. Each gigabyte corresponds to a billion bytes and every billion bytes is 8 billion bits.
