Abstract

PURPOSE: To select either a NAND gate or a NOR gate to be in the operating state by connecting each input terminal and output terminal of the NAND gate and the NOR gate in parallel, and supplying a signal to a control terminal externally.
CONSTITUTION: With the signal of H level fed to a control terminal Z, an L level signal is supplied to a control terminal inverse of Z, the transistor(TR) QP1Z of a high voltage switch 3 and a TR QN1 inverse of Z of a low voltage changeover switch 4 are turned off, conversely a TR QP1 inverse of Z and the TR QN1Z of a NAND gate 6 are turned on. Thus, a logic integrated circuit acts like a NAND gate 6. Conversely, with the signal of L level fed to the control terminal Z, since the switches 3, 4 are thrown to the opposite position, the logic integrated circuit acts like a NOR gate 5.
