Electrical Engineering/Integrated circuit pin numbers.


Dear Prof Cleggsan

Is it logical and practical to design Integrated circuit which can have odd number of pins?.

This will take the Triangle, Pentagon, Septagon etc shapes for IC.


Any number of pins may be designed into an IC. However, if you step away from the standard packages that all the fabricating houses adhere to it will run up the developmental costs considerably. Of course, one can use the pin designation for standard package and just not use all of them.

Many custom ICs have blank pins.

As to shape of the IC package, again it is convention and sticking to industry standards.
