A CMOS inverter circuit is coupled to a power source by a cut-off circuit which prevents current flow through the CMOS inverter circuit when the input signal to the CMOS inverter is of a first bi-level state. The cut-off circuit responds to the output signal from a second inverter circuit that is connected to receive the output of the CMOS inverter circuit. A second embodiment of the invention provides a latching function by connecting a feedback path from the output of the second inverter circuit to a toggle gate circuit connected to the input to said CMOS inverter circuit.
