ABSTRACT:
A high speed, unity gain, emitter follower OR circuit is disclosed including first and second pairs of emitter-connected complementary bipolar transistors with the bases of the NPN transistors being connected together and the bases of the PNP transistors being connected commonly to an input line. One of the NPN transistors id diode-connected (base to collector). The emitter of the other NPN transistor is connected to an output terminal. The input line is connected to the emitters of a pair of OR input NPN transistors and to a first current source. A second current source is coupled to the diode-connected NPN transistor.
