ABSTRACT:
An improved TTL to ECL translator circuit having voltage gain is described. First and second transistors are provided, with the base of the second transistor coupled to the collector of the first transistor. The emitter of the second transistor is coupled through a voltage level shifting means to the ECL output. The base of the first transistor is coupled to the TTL input. A clamping means coupled to the collector of the first transistor limits the maximum voltage at the collector.
