Above eighty percent of the IC market has been captured by digital ICs which are mostly utilize by the computer industry.
Digital IC lend themselves easily to monolithic integration because a Computer uses a large number of identical circuits.
Moreover, such circuits employ relatively few capacitors and values of resistances, voltages and currents are low.
Digital ICs contain circuits whose input and output voltages are limited to two possible Level low or high.
It is so because digital signals are usually binary. Sometimes, digital circuits are referred to as switching circuits.
Digital ICs include circuits such as,
- Logic gates
- Clock chips
- Calculator chip
- Memory chip
