Abstract

coupling of signals between Large Scale Integrated Circuit chips is facilitated by provision of an emitter follower output stage for the chip. Special input circuits are also provided. The logic circuits may be DTL or Schottky TTL. The special input circuit may be a DTL type or a CTL (complementary transistor logic) type. Pull down resistors may be employed with the emitter follower output driver and the special DTL input circuit.
