Several digital bipolar logic circuits are described, for applications as digital logic gates and for buffering and level-shifting. These circuits are adapted for high-speed operation, and they have reduced supply-voltage requirements. In each of these circuits, a control device such as a transistor (Q3.5; Q3.6) turns an input circuit (Q3.1, Q3.2: Q3.3, Q3.4) on or off by means of an emitter-to-emitter connection. However, unlike most conventional ECL circuits, these circuits avoid stacked transistor configurations. <IMAGE> |
