Abstract of the Disclosure A multi emitter multi input BICMOS NAND circuit is provided wherein an output node OUT connected to an output terminal is coupled between pull up and pull down blocks. According to one embodiment of the present invention, the pull up block is comprised of a plurality of identical basic cells, each comprised of a CMOS inverter driving an NPM pull up transistor mounted as an emitter follower. Logic signals are applied on the inputs of the inverters, and the inverted signal (A31, A32) is available at the emitter of the emitter follower which corresponds to the output of the cell. All outputs are tied altogether to perform an OR function and are connected to said …
