ABSTRACT:
Additional transistors are serially inserted in a level conversion circuit that configures a flip-flop with N channel transistors and P channel transistors and that outputs TTL level output signals by converting ECL level input signals, so that said additional transistors are turned OFF at the same time as the P channel transistors, connected serially with the N channel transistors, are turned ON. This above described process will prevent a through current flowing between positive and negative power sources, when transistors are switched, thus preventing an increase in the current consumed.
