ABSTRACT:
An onboard structure used to terminate standard ECL devices of non-gate array devices which save space on the multichip module by requiring only non-discrete components. These non-discrete components include a first transistor having its collector coupled to the emitter of a second transistor, and its based coupled to the collector of a third transistor. Different variations of the onboard structure permit the structure to be a 50 ohm output, a 25 ohm output, a 60 ohm output, a series terminated output or a current sourced input termination.
