ECL Circuit for forcibly setting a high level output

摘要

An ECL circuit includes a differential pair of transistors, a set transistor, and a set resistor connected between the emitters of the differential pair of transistors and the emitter of the set transistor. The output of the ECL circuit can be fixed securely to a "high" level only by applying a "high" level signal having the same level as the "high" level signal of the data input to the base of the set transistor.
