Figure 4.24. There are two sets of terminals, two inputs on the left and two outputs on the right. The lower terminals on each side are grounded. The upper input terminal connects to the gate of an N channel enhancement mode MOSFET and also to the gate of a P channel enhancement mode MOSFET. The source of the N channel is grounded and the drain connects to the drain of the P channel. The source of the P channel connects to V sub DD. The upper output terminal connects to the junction of the two drains. End verbal description.
