ABSTRACT:
An output stage suitable for monolithic semiconductor IC uses is disclosed. The stage employs a pair conventional NPN output transistors biased and driven with conventional bipolar IC elements. The pull up device, which sources output current for positive or rising inputs, is maintained on for negative signal swings so that it can be used to bias the pull down device which is cut off for positive signal swings.
