Key Takeaways:
-
Integrated circuits (ICs) are named based on their function, manufacturer, or a combination of both.
-
The JEDEC Solid State Technology Association establishes naming conventions for ICs.
-
The naming scheme includes a prefix, a number, and a suffix indicating the package type.
-
Manufacturers often use their own unique numbering systems for their ICs.
-
ICs can have additional suffixes indicating their temperature range, voltage range, or other characteristics.
How are ICs Named?
Function-Based Naming
-
ICs are often named based on their primary function.
-
Examples include microcontrollers, microprocessors, memory chips, and logic gates.
-
The name of the IC clearly indicates its purpose within an electronic system.
Manufacturer-Based Naming
-
Manufacturers often create their own naming conventions for ICs.
-
They may use a combination of letters and numbers to identify specific ICs.
-
For example, Texas Instruments uses the prefix “SN” for its integrated circuits.
Combination of Function and Manufacturer
-
Many ICs are named using a combination of their function and manufacturer.
-
This provides a more descriptive name that helps distinguish between different types of ICs.
-
Example: The 74LS04 is a TTL logic quad 2-input NAND gate from Texas Instruments.
JEDEC Standards
-
The JEDEC Solid State Technology Association has established guidelines for IC naming conventions.
-
These guidelines help ensure consistency in IC naming across different manufacturers.
-
The JEDEC numbering system includes a prefix, a number, and a suffix indicating the package type.
Prefixes
-
The prefix indicates the type of IC.
-
Examples include “SN” for small outline ICs and “DIP” for dual in-line packages.
Numbers
-
The number indicates the specific function or application of the IC.
-
For example, the number “74” indicates TTL logic family.
Suffixes
-
The suffix indicates the package type.
-
Examples include “SOIC” for small outline integrated circuit and “BGA” for ball grid array.
Additional Suffixes
-
ICs may also have additional suffixes indicating their temperature range, voltage range, or other characteristics.
-
Example: The suffix “-E” indicates extended temperature range, and the suffix “-V” indicates a higher voltage range.
