Where are discrete logic ICs (7400 series logic chips) used in industry and why?

Today, surface-mounted CMOS versions of the 7400 series are used in various applications in electronics and for glue logic in computers and industrial electronics. The original through-hole devices in dual in-line packages (DIP/DIL) were the mainstay of the industry for many decades.

Where are discrete logic ICs used in industry?

By 1961, both Fairchild and TI were making available off-the-shelf logic circuits. By 1964, a higher-speed logic structure, diode-transistor logic (DTL), was created to build a wide array of logic functions. Meanwhile, other companies developed a form of transistor-coupled logic.

Where are discrete logic chips used?

Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also manufactured. These chips are used as "glue chips" between ASICs and other ICs typically to reshape and transfer signals. See logic gate and glue logic.

What is the function of IC 7400?

7400 IC is the most widely used TTL (Transistor-Transistor Logic) device in the world. It contains four independent two-input NAND gates. Its popularity is based on the fact that any logic gate function can be created using only NAND gates.

What is the meaning of 7400 series?

7400 series is an extended family of digital integrated circuits. Chips in this series include a variety of discrete logic chips chips such as and gates and or gates as well as registers, decoders, and RAM units.

What is the difference between the 7400 series and the 5400 series?

The main difference between the two was the temperature range; 5400-series devices generally operated from -55 to 125C, while the 7400 parts, housed in inexpensive plastic packages, were rated from 0 to 70C.

What is the difference between 7400 and 74LS00?

The 74LS00 family improves technically on the 7400 family in two key areas: faster speed and lower power consumption. The only limitation of the 74LS00 family compared to the 7400 family is that the 74LS00 family can only source half as much current.

What is the advantage to using discrete logic?

The big advantage is you need much less space on the board, routing is much simpler, and you can easily change the logic functions if required. The remaining use-case for separate logic ICs is when things have to work quicker than 1µs.

What do you mean by discrete logic gates?

Filters. A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also manufactured.

What is IC 7400 NAND gate?

IC 7400 is fourteen pin Logic Gate IC.

The IC 7400 consist of four NAND Gates. The NAND Gate is also called Universal Gate. The NAND gate has a total of three terminals, two inputs terminals, and one output terminal. All NAND Gates are independent. IC 7400 is also called Quad 2-input NAND Gate IC.

How many and circuits are contained in a 7400 NAND IC?

Explanation: 7400 IC's pin has total 14 pin. Pin no 7 use for GND and pin no 14 used for +vcc and remaining pins used for connections. For a NAND gate two inputs are required and one output is obtained means for NAND gate 3 pin connections are required. Thus, a 7400IC contains 4 NAND gates with each having 3 pins.

Why it is called IC 7400?

7400 7402. mentions that it has dual inline package and 7 pins each side. 4 represents number of gates last two digits r meant for type code.

What is the function of pin 7 and 14 of IC 7400?

For most of the 7400 chips, pin 7 is the ground (GND) connection and pin 14 is the +5V power supply. There are exceptions like the 7490. 2.0V or higher signifies a logical "1"; 0.8V or lower signifies a logical "0".

What are Logic ICS?

A logic IC is a semiconductor device that implements a basic logical operation that is performed on one or more digital input signals (represented by 1 and 0 or H and L) to produce a digital output signal.

Who invented 7400 Series?

The following is a list of 7400-series digital logic integrated circuits. In the mid-1960s, the original 7400-series integrated circuits were introduced by Texas Instruments with the prefix "SN" to create the name SN74xx.

How many NAND gates are there in a single 7400 NAND gate IC?

The number of pins a logic IC may commonly have are 14 or 16. A 7400 consists of four NAND gates, with 2 input pins and 1 output pin for each of the gates, and also a pair of pins for the power supply inputs, pin 14 and pin 7.

Is TTL logic still used?

The term "TTL" is applied to many successive generations of bipolar logic, with gradual improvements in speed and power consumption over about two decades. The most recently introduced family 74Fxx is still sold today (as of 2019), and was widely used into the late 90s.
