UNIT 8: INTEGRATED CIRCUITS (ICs) INTRODUCTION An integrated circuit (IC) is a tiny chip that contains thousands or millions of transistors. ICs are the brains of modern electron- ics. They are found in computers, phones, cars, and appliances. STORY 1: What is an IC? An IC is a small piece of silicon. Engineers design circuits and print them onto the silicon. The chip is then placed in a plastic or ceramic package with metal pins. The pins connect the IC to the circuit board. Common ICs inc
