Abstract
Protection for the transmission of higher amplitude outputs required of differential amplifiers formed by thin oxide transistors with limited maximum voltage tolerance used where compliance with communication protocol standards requires handling voltages which may, in transition, exceed desirable levels is provided by limiting the voltage across any two device terminals under power down conditions.
