Digital Integrated Circuits (ICs) are at the heart of various digital products. They are made up of logic gates, which are the basic building blocks of digital electronics. Logic gates are simple digital circuits that take one or more binary inputs and give a single binary output. There are seven basic logic gates: AND, OR, NOT, NAND, NOR, XOR, and XNOR.

Here's a step-by-step explanation of how a digital IC works with respect to logic gates:

1. **Input Signals**: The process begins when the IC receives binary input signals. These signals are in the form of voltage levels, where a high voltage typically represents a binary '1' and a low voltage represents a binary '0'.

2. **Logic Gates Processing**: These input signals are then processed by the logic gates within the IC. Each logic gate performs a specific logical function on the input signals. For example, an AND gate will output a '1' only if all its inputs are '1'. An OR gate will output a '1' if any of its inputs are '1'. A NOT gate will invert its input, outputting a '0' if its input is '1' and vice versa.

3. **Combination of Logic Gates**: In a digital IC, these logic gates are combined in various ways to perform complex logical functions. For example, a NAND gate is a combination of an AND gate and a NOT gate. It outputs a '0' only if all its inputs are '1'. Similarly, a NOR gate is a combination of an OR gate and a NOT gate. It outputs a '0' if any of its inputs are '1'.

4. **Output Signals**: After the input signals have been processed by the logic gates, the IC outputs the resulting binary signals. These output signals can then be used by other components in the digital system.

5. **Feedback**: In some cases, the output of a logic gate can be fed back as an input to the same or a different logic gate. This allows the IC to perform more complex operations and to store information, as in the case of memory circuits.

In summary, a digital IC works by receiving binary input signals, processing these signals through a series of logic gates, and outputting the resulting binary signals. The specific operation of the IC depends on the arrangement and types of logic gates it contains.
