ABSTRACT:
The present invention is directed to a decoder implemented with metal oxide semiconductor (MOS) field effect transistors (FETs) and a bipolar transistor in a collector-follower configuration. In one embodiment, NPN transistors perform decoding, FETs are used as pull-up devices and a PNP transistor in a collector-follower configuration is used to drive the output line. In a second embodiment, FETs perform decoding and are used as pull-up devices, and a PNP in a collector-follower configuration is used to drive the output line.
