Abstract

A logic level translator uses a current switch, a current source and a plurality of cathode followers to convert T.sup.2 L and DTL level binary signals into CML and ECL level binary signals. The translator provides isolation between the T.sup.2 L ground and the CML ground so that noise in the CML signals is reduced.
