Transition detection circuit

摘要

A transition detection circuit comprises an inverter circuit for inverting an input signal, an S-R flip-flop circuit receiving the input signal at one of its input terminals and the inverted input signal at the other input terminal, and having a time difference between the transitions of the signals at the output terminals; and a coincidence detection circuit receiving the output signals from the output terminals of the flip-flop circuit and generating a coincidence detection signal when the output signals are both at the same and specific logic level. The coincidence detection signal serves to represent a transition of logic level of the input signal.
