An integrated circuit is provided which includes a multi-state circuit
with a first PMOS transistor and a first NMOS transistor. In an active
mode, the multi-state circuit is operable to switch between a first state
in which the first PMOS transistor is turned on and the first NMOS
transistor is turned off and a second state in which the first PMOS
transistor is turned off and the first NMOS transistor is turned on. A
power source NMOS transistor has a drain connected to a supply voltage
terminal and has a source connected to a source of the first PMOS
transistor. A power source PMOS transistor has a drain connected to a an
effective ground terminal and has a source connected to a source of the
first NMOS transistor.
