Although the automotive market has slowed down and the forecast for automotive semiconductors has been revised downward, these new technologies will still improve the performance of automotive semiconductors and bring about technological changes...

Optical isolators are widely used in fiber optic communication systems, fiber optic sensing systems, and fiber optic lasers. The basic and common principle of optical isolators is the Faraday effect.

The 7408 integrated circuit is a classic TTL (transistor-transistor logic) type IC, which is widely used in various digital circuits. It contains four 2-input AND gates, each with two inputs and one output, for performing logical AND operations.
