PURPOSE:To simplify the circuit constitution by constituting a circuit deciding logic with a circuit comprising both a pMOS transistor (TR) and an nMOS TR to decrease an input signal in the logical decision circuit. CONSTITUTION:The logical decision circuit L2 consists of the pMOS TR and the nMOS TR. An input affirmative signal is used as a serial gate input signal and it is turned off when the input affirmative signal is a high level and the MOS TR is turned off when the signal is at a low level. Thus, since all the MOS TRs included in the logical decision circuit L2 are operated by the input affirmative signal only, the number of input signal lines is less. |
