ABSTRACT:
A circuit for detecting the transitions of an input signal between first and second voltage levels includes first and second signal paths connected between a first point of operating potential and an output point. Each signal path includes first and second transistors having their conduction channels connected in series. In response to an input signal of the first level the first transistor of one path is turned on while the first transistor of the other path is turned off and in response to an input signal of the second level the first transistor of the one path is turned off while the first transistor of the other path is turned on. The second transistor of each path is turned off a first time delay after the first transistor of that path is turned on and is turned on a second time delay after the first transistor of that path is turned off. Consequently, one signal path produces a relatively low impedance conduction path for input signal transitions of one polarity during the first time delay and the other signal path produces a relatively low impedance conduction path for input signal transitions of opposite polarity during the second time delay.
