The IC product code, also known as the manufacturer code or part number, is a unique identifier assigned to integrated circuits ICs by their manufacturers. These codes typically consist of alphanumeric characters and vary in length depending on the manufacturer's conventions. They serve to differentiate one IC from another and provide information about the specific model, characteristics, and manufacturer of the IC. While they are intended to be unique identifiers, there can be cases of overlap or similarities between different manufacturers' codes. The numbers on an integrated circuit IC typically refer to the part number or manufacturer code, which provide information about the semiconductor, use, type, make, and other characteristics of the IC.

Integrated circuits ICs come in many variants and are available from many manufacturers. ICs with similar functions can look very different, while ICs with different functions can look similar. The internal structure and mechanical tolerances of ICs can also be quite varied, and choosing the wrong IC can be detrimental to an electronic design. Engineers and designers need a clear way to differentiate between ICs for their projects. IC manufacturer codes give designers this information, allowing them to be confident in their component choices. IC manufacturer codes are identifying codes placed on integrated circuits by electronics manufacturers.

Last updated: July 3, It was about the same length and weight as two to three double-decker buses and contained 18, buzzing electronic switches known as vacuum tubes. Despite its gargantuan size, it was about a billion times less powerful than a modern laptop—a machine about times smaller. If the history of computing sounds like a magic trick—squeezing more and more power into less and less space—it is! What made it possible was the invention of the integrated circuit IC in It's a neat way of cramming hundreds, thousands, millions, or even billions of electronic components onto tiny chips of silicon no bigger than a fingernail. Let's take a closer look at ICs and how they work! Photo: An integrated circuit from the outside.

Integrated circuit marking codes

This data base is only a couple of years old judging from the Wayback Machine, but seems to be fairly exhaustive and can be found referenced in quite a few electronics forums. Unlike their larger SMD siblings, these chips in question are so small that there is no room to print the entire part number on the device. Instead, the standard practice is for manufacturers use an abbreviated code of just a few characters. And just because it is standard practice does not imply the marking codes themselves follow any standard whatsoever. Several sites like the one [JohnK] found have been around for years, and adding yet another database to your toolbox is a good thing.

Hoping that AD will change the culture. List of IC Manufacturer Codes. If there's a notch, Pin 1 is usually on the upper-left side of the notch. Determine the Calendar Year: The first two digits of the date code represent the last two digits of the calendar year in which the IC was manufactured. Ultra Librarian uses verified IC manufacturer codes to help designers unambiguously identify the components they need. Hi All, The trick was the one Jeff showed above. PCB Footprints. How did you find it? More than datasheets- audio application integrated circuits such as preamplifiers, volume and tone controller, audio processor, audio power amplifier available on your collection. The "74" in an IC part number typically indicates that the IC is a member of the series of integrated circuits. Here are the key characteristics of the IC:. Adjust for the First Week : Manufacturers often consider the first week of the year as the week in which the first Thursday of the year falls. This method of identifying ICs has been used in Europe in various forms since the s. Join Our Newsletter Subscribe to our newsletter to receive the latest news, and important updates. Pinout Diagram: The standard pinout diagram for the IC is as follows:.

A microchip containing an integrated circuit. Hi, I would like some help identifying a part by its markings. While they are intended to be unique identifiers, there can be cases of overlap or similarities between different manufacturers' codes. By understanding these numbers, engineers and technicians can easily identify and choose the right IC for their application. Although IC manufacturer codes are meant to be unique, this is rarely the case. They are encapsulated in plastic dual-in-line packages DIPs with a specific pin configuration, such as pin, pin, or pin DIPs. The numbers on an integrated circuit IC typically refer to the part number or manufacturer code, which provide information about the semiconductor, use, type, make, and other characteristics of the IC. PCB Footprints. Engineers and designers need a clear way to differentiate between ICs for their projects. Placing an order. Ultra Librarian uses verified IC manufacturer codes to help designers unambiguously identify the components they need. Email Required. Cheers, heke. Manufacturers supplying international markets may also need to assign multiple codes to the same component, depending on the region and the expectations of their markets. Reading IC date codes typically involves understanding the format used by manufacturers to encode the manufacturing date of the integrated circuit.
