PURPOSE:To eliminate the need for separately forming a chip for a level converting circuit, and to obtain high-speed properties and high reliability by forming output circuits having different output levels on the same chip and selectively connecting the output circuits to output terminals. CONSTITUTION:A plurality of output circuits 32a, 32b having different output levels are formed onto a semiconductor chip 31, and connected selectively to output terminals 33 by wirings 34. Accordingly, a level converting circuit shaped onto several chip need not be used, thus reducing connections among the terminals, then acquiring high-speed properties and high reliability. |
