Abstract
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 turns an input circuit on or off by means of an emitter-to-emitter connection. However, unlike most conventional ECL circuits, these circuits avoid stacked transistor configurations.
