ABSTRACT:
A digital circuit pulls up an output node using an NFET device. The digital circuit is part of a CMOS predriver having balanced delays for coming out of tristate mode and for data mode operation. The predriver has size and speed capability advantages and is particularly advantageous when followed by a CMOS driver powered by a lower positive voltage supply.
