ABSTRACT:
A TTL/ECL translation circuit for translating TTL level input signals, which have a high voltage state and a low voltage state, to ECL level output signals, which have a high voltage state and a low voltage state. The translation circuit includes a TTL input circuit, a level shifter, and an ECL output circuit connected in series. The TTL input circuit receives the TTL level input signals and generates a first intermediate signal, corresponding to the TTL level input signals, that is transmitted to the level shifter. The level shifter receives the first intermediate signal and generates a second intermediate signal corresponding to the first intermediate signal that is transmitted to the ECL output circuit. The ECL output circuit receives the second intermediate signal and generates an ECL output signal corresponding to the second intermediate signal and the TTL input signal.
