摘要：
A parallel EXCLUSIVE OR and EXCLUSIVE NOR gate comprises four groups of three transistors. In each group of transistors, one (60,62,66,70) is part of the EXCLUSIVE NOR gate only, one (74,76,78,80) is part of the EXCLUSIVE OR gate only, and one (56,58,64,68) is a part of both gates. The gates may be constructed in a manner similar to a known circuit using tri-inverters, but since one transistor in every group of three has a dual membership of both gates, the total circuit requires 12 transistors instead of 16.
