Identifying ICs

 

1) All ICs have useful datasheets which can be found by entering the part # into google or seaching through online retailers such as digikey.com, or mouser.com

2) Datasheets contain package information, electrical information, pin diagram, and hopefully application notes. Datasheets are your friend.

3) ICs come in a variety of packages.

4) Surface mount components are extra small and are not meant for prototyping. You will be sad if you buy these by mistake.

5) DIP (Dual in line package) have pins spaced .1 inches apart, just like your breadboard. DIPs are your friend.

5) The top of an IC is typically marked with a notch or dot, or both.

5) Pins are numbered counterclockwise, starting in the upper left.
