Pass Transistor Logic. In complementary cmos logic primary inputs are allowed to drive only gate terminals. The bottom line with pass transistor logic is that you are trading electrical performance for the possibility of reducing transistor count.
The loss in electrical performance is especially disconcerting when the pass block functionality is provided by an nmos transistor instead of a cmos transmission gate see this article for more information. An example of pass transistor logic. The standard cmos multiplexer in a way it is not surprising that ptl leads to efficient multiplexers.

Pass transistor logic for xor gate. Pass transistor logic ptl also known as transmission gate logic is based on the use of mosfets as switches rather than as inverters. The standard cmos multiplexer in a way it is not surprising that ptl leads to efficient multiplexers. Pass transistor logic working is given below.
