Integrated injection logic or merged transistor logic is a novel bipolar circuit design approach to achieve high-density large-scale integration. As the basic logic units it uses multicollector npn transistors which are powered from merged multicollector lateral pnp transistors. I<sup>2</sup>L can be fabricated with standard buried collector technology and is therefore compatible with conventional bipolar circuitry on the same chip. The feature of having special interface circuitry?digital and/or linear?on the same chip renders I<sup>2</sup>L a powerful LSI technique.
