I2L: Coexistence with NMOS

I

L or, more simply, injection logic, presents significant advantages over n-channel MOS technology in two major areas: products that must operate at high speeds and applications that require analog and digital functions to be combined on the same chip. Seeking to exploit the potential advantages fully, Fairchild has applied dielectric-isolation techniques to I

L and come up with a speed-and density-enhancing version called Isoplanar integrated-injection logic, or I
