Is it possible to have an odd pin ic and if not then why ic having only even number of pins exist?

for simplicity of calculation of no of pins


I have a not functional lego NXT 2.0 it has two things burned a resistor 472 and a 6 pins ic of code K1- whats that ic?

Sorry, the IC is probably only marked with what is called a "house number", these are proprietary. It may even be a custom device ONLY made for Lego.

Why IC's have even no of pins?

I would guess its because an even number of IC pins is aesthetically pleasing. Odd numbers of IC pins are certainly possible if you manually cut off a redundant ground pin. Even in a field such as semiconductor engineering that is apparently removed from the luxury of aesthetics---yielding to maximum packaging efficency---there is still a moderate appeal to make the chip packing aesthetically pleasing because it makes the IC chips appear more organized on the board and easier to count the pin numbers to locate a pin when debugging by counting in 2's. On the other hand, one easily argue for changing the packaging to an odd number of pins so that automation processing equipment can automatically detect the package orientation. (One could only hope that engineers that work on IC design would have the same philosopy of aesthetics when engineering the internal structures within the IC because the internal structures of an IC design are some of the most messy structures on earth. For example, its often better to sacrifice a little but of space in the name of readability in the IC design code and Extra care needs to be taken to organise the abundance of interconnections between millions of other points in an IC design and to give each signal a name that groups signal bundles together. In contrast the pin names exposed on the outside of the IC are not really so well selected sometime. Especially where there is multiplexing of pin functions, ie. sharing of pin functions of the IC to reuse the pins and save space when the IC is in certain usage mode, thus in this case you might have an odd or even number of virtual pins who's functional changes depending on the IC's shared pins settings. This is all more than you ever wanted to know. )


How do you add 8 bit number with diagram of various IC pin?

for addition of 8 numbers by IC , first we have to connect all bit numbers on different pins of IC & then take the output on remaining pins , For these first we have to make a program for vhdl in FPGA (field programmable gate array) & proceed accordingly .


How many pins does a 7805 IC have?

The 7805 regulator IC has three pins; input, output, and ground. The case is also a pin, but it is grounded, so there are still only three pins, for all practical purposes.
