Abstract

PURPOSE:To obtain a desired characteristic by realizing each logical function of the standard logical circuit group by means of a separate circuit system, and providing a signal level converting circuit on the input/output parts. CONSTITUTION:Signal level converting circuits 1, 2 are provided on the input/ output parts respectively of the blocks A'-F' which have realized the same logical function as each logical function unit (block) of the standard SSI, MSI (small scale or medium scale integrated circuit group), by means of a separate circuit system which is separate from SSI and MSI. Accordingly, the logical function and the signal level of LSI, which are seen from the outside can be made equivalent entirely. Moreover, the characteristic of LSI can be made a desired characteristic according to the circuit system.
