| Not only Logic (Digital) ICs are way
more powerful, when compared to analog electronics, but they are also a lot easier to work with. In fact,
designing digital electronics may be as simple as playing with a Lego game. All you need for that is a good
start--our book Learn Hardware Firmware and Software Design is excellent for that! Many logic ICs are standard components built by many manufacturers. That is very important when designing hardware, because you are not constrained to one manufacturer only. Always try to use only standard components in your designs. In addition, you should remember that in firmware we can implement any hardware function. For example, an 8 pins Microchip controller of about 0.5 USD may be an excellent local driver, replacing few expensive ICs, and having plenty of upgradeable firmware intelligence. Firmware intelligence should always be preferred to hardware logic. In this page are highlighted few standard Logic ICs, but you should be aware they are way more. The structure used to present families of ICs is: 1. Types of standard ICs 2. Standard Logic ICs NOTE The basic notions highlighted in this page are related to electronic design topics presented in the first part Hardware Design of Learn Hardware Firmware and Software Design. |

There are five major types of standard Logic ICs: 1. Resistor Transistor Logic (RTL) 2. Diode Transistor Logic (DTL) 3. Transistor-Transistor Logic (TTL) 4. Emitter Coupled Logic (ECL) 5. Complementary MOS LOGIC (CMOS) Only TTL and CMOS types are presented here because they are the most important.

There are many standard ICs. Following are presented just few of the most interesting, but you should study this subject seriously.
The advantage of using standard Logic ICs is, they simplify your work a lot, and they come with
very low prices. Learn Hardware Firmware and Software Design book presents few
excellent applications of hardware and firmware implementation of logic ICs. For example, the SPI BUS,
Multiplexing, Seven-Segments display, SIPO, PISO, etc. |
