Abstract

Disclosed is a new approach to implement an ECL logic function in which at least one of the inputs is an over-writing control, i.e., when an input causes the logic output to be at either a logical 1 or 0, irrespective of the other inputs. The new approach, in general, will save power, require less space, or improve speed or a combination of these, when compared with other known approaches when only non-inverted inputs are available. This is particularly useful in a VLSI environment, where similiar functional blocks may be encountered hundreds of times.
