ABSTRACT:
This invention relates to interfacing high speed, low voltage, data streams with CMOS circuits and, more specifically, to converting low voltage, differential, ECL signal levels to higher voltage levels which are compatible with CMOS circuits while maintaining high speed and sufficient drive capability for larger system applications. This is accomplished primarily by making the first stage inverters 5 and 6 as geometrically small as possible and providing additional cross-coupled buffers 7 and 8 capable of driving large capacitive loads.
