ABSTRACT:
The decode circuit utilizes NPN and PNP transistors and performs a complete decode function in only one logic level with the no need for a true/complement input of each binary input. A first embodiment of the decoder provides an UP level output when selected. A second embodiment of the decoder provides a DOWN level output when selected. The decode circuit may be used as an address decode circuit in a memory and also portion(s) of the decode circuit may be used independently as a binary logic circuit. Also disclosed is a complementary current switch logic circuit with dual phase outputs.
