Abstract

PURPOSE:To prevent a latch-up state and the destruction of an element by providing switching means between a couple of inverters differing in power voltage and a power source and by exercising complementary control over those switching means. CONSTITUTION:When a control signal is at level [L], MOS transistors T1 and T4 are on and MOS transistors T5 and T8 are off, enabling inverters of transistors T2 and T3 to operate with outputs at VSS1 and VDD1. When the control signal is at level [H], MOS transistors T1 and T4 are on and T5 and T8 are off, enabling inverters of transistors T2 and T3 to operate with outputs at VSS2 and VDD2.
