Here you can find a large collection of semiconductor IC consist of Optocoupler, Microcontroller, Interface, Amplifier and many more ICs. An integrated circuit (IC), sometimes called a chip or microchip, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated. This semiconductor IC can function as an amplifier, oscillator, timer, counter, computer memory, or microprocessor. Each IC is useful for a specific function.
