ABSTRACT:
An ECL latch circuit includes a logic section and has a reset or set function. The logic section includes a first to seventh transistors. The third transistor has a collector connected to the collector of the first transistor, and a base for receiving a first reference potential or the collector potential of the second transistor through an emitter follower section. The fourth transistor has a collector connected to the collector of the second transistor, a base for receiving a collector potential of the first transistor through an emitter follower section or receiving a first reference potential, and an emitter connected to the emitter of the third transistor. The fifth transistor has a collector connected to the collector of the second or first transistor, a base for receiving a reset or set signal, and an emitter connected to the emitter of the third transistor.
