A BIMOS logic gate (10) comprises a differential circuit having a common biasing network (14). A MOS transistor (16) in one portion of the differential circuit receives a MOS level input signal (36) and provides an ECL level output signal (34). A bipolar transistor (20) is biased by a complementary ECL level input signal 32'. The other portion of the differential circuit includes a bipolar transistor (30) that is biased by an ECL level input signal 32. The emitter coupled transistors 20 and 30, receiving complementary ECL level inputs, along with the MOS transistor 36, receiving MOS level inputs, combine to provide logic functions with ECL level outputs 34 and 34'.
