IC PINOUTSThe following list covers just a few of the IC's on the market and these are the "simple" or "basic" or "digital" or "op-amp" IC's suitable for experimenting.
When designing a circuit around an IC, you have to remember two things: 1. Is the IC still available? and 2. Can the circuit be designed around a microcontroller? Sometimes a circuit using say 3 or 4 IC's can be re-designed around an 8-pin or 16-pin microcontroller and the program can be be kept from prying eyes due to a feature called "code protection." A microcontroller project is more up-to-date, can be cheaper and can be re-programmed to alter the features. This will be covered in the next eBook. It is worth remembering - as it is the way of the future. |
