Circuit arrangement for converting ECL-logic signals to TTL-logic signals

摘要

A circuit arrangement for level conversion of ECL-logic levels to TTL-logic levels, having an emitter-coupled current switch with an input addressable by ECL-logic levels, and a TTL-logic output stage, includes a voltage-controlled current source having an input addressable by an output of the current switch, and having an output connected to the TTL-logic output stage.
