ABSTRACT:
A high speed circuit for converting CML/ECL gate signals to TTL gate signals. The circuit includes two parallel current paths coupled to a current mirror section in which uniform current is maintained in portions of each path. Each current path includes a transistor which is coupled to the CML/ECL gate for sensing the differential voltage in the gate. The TTL gate is coupled to one of the current paths which steer current into or out of the TTL gate depending upon the differential voltage sensed in the CML/ECL gate.
