Practical Electronics/IC/4007

The 4007 integrated circuit contains three complementary enhancement-mode MOSFET pairs. One pair has connections to the drain terminals, one to the source terminals and the commoned drains (i.e. it is wired as an inverter) and one allows access to all source and drain connections. All pairs have the gate terminals commoned and available. The bulk connections are to the power rails (VDD for the p-channel devices and VSS for the n-channel devices).
