ABSTRACT:
An address transition detector circuit according to the present invention comprises an input terminal, a one-shot pulse generator circuit having an input electrically connected to the input terminal, a first switching device electrically connected between a first and second nodes and brought into a conducting state in response to a one-shot pulse output from the one-shot pulse generator circuit, a second switching device electrically connected between a ground potential node and the second node and driven in response to a signal input to the input terminal, a plurality of switching devices parallel-connected between the first and second nodes and respectively driven in response to a plurality of address transition one-shot pulse signals, and power source potential supplying means for supplying a power source potential to the first node. Therefore, the address transition detector circuit can prevent malfunctions from occurring even if a change in the input signal and an address transition take place at the same time.
