i need internal circuits of various IC?
409039
Just google the IC number + datasheet and you should be able to find the data sheets for most of those components.  If you read the sheet properly, it will tell you what the internal circuit is.

Use a darlington array. They make them with 6 or more darlington transistors on a single chip. Some even have the circuit protection diodes built in. These are perfect for stepper motor control circuits. If you don't want to buy them, you can probably scavenge a couple from a dead printer or copier, if you can get one.\n\nOther than that, there is no best transistor. This is a general, low speed switching application, and almost any transistor that can handle 160mA at your circuit's voltage can be made to work with the proper biasing. But a single chip to replace several transistors and diodes will simplify your PCB.

I would suggest, if you can still find some, seven segment hexadecimal driver IC's.  They will convert discrete logic bits into the necessary outputs for a seven segment display.\n\nThe chip has unfortunately been discontinued and are a little fun to find now.  You can build up a substitute using logic gates or a FPGA (if you have access to those and the related equipment).\n\nThis site might be helpful...

Your question is very vague.\n\nGive more description as what you want. or contacta  hardware engineer.

start with the datasheet\nhttp://www.atmel.com/dyn/resources/prod_documents/DOC0839.PDF\nthen look in the I/O ection to design the interface crcuits\n\nthen you have to get a programmer and compiler that will work for that chip. Often they have evaluation circuits that will help you get started. Check the mfg website for something of that nature.

u can go to library.alldata.com and be able to find the wiring schematic. or sometimes u can call a local parts store and they can print one out for you.

You can buy them in chip form. I think Analog Devices makes them, up to eight bit. They are easier to use and more accurate than anything ou could build from discrete parts.

Here is a good article on what goes into making a chip and this goes for most memory as well.\n\nhttp://en.wikipedia.org/wiki/Integrated_circuit
