Abstract

PURPOSE:To avoid the influence of noise upon the input level to prevent malfunctions, by using the input control signal different in phase from the fundamental clock signal of the circit unit in case that the input signal is latched into the memory circuit. CONSTITUTION:In the circuit unit including memory circuit LATCH, clock input X id divided into the 1/2 frequency by flip-flop FF1, and the output is used as the fundamental clock signal in the circuit. A clock signal later than this fundamental clock signal by the 1/4 period is generated by flip-flop FF2, and signal phi*. SET is generated from this signal and the input control signal and is latched into input signal IN latch circuit LATCH. Since the input signal later than the clock signal by the 1/4 period is latched into the memory circuit fundametally in this method, the potential of the input pin is read when no noise is put on the ground level.
