ABSTRACT:
An input signal translating circuit includes first and second transistors having their conduction paths connected in series between a first power terminal and an output node, and a third transistor whose conduction path is connected between the output node and a second power terminal. The circuit includes means for applying an input signal to the control electrodes of the first and third transistors for turning one on and the other off for one value of the input signal and turning the one off and the other on for another value of input signal. Means responsive to the signal produced at the output node generate a delayed negative feedback signal which is applied to the control electrode of the second transistor for turning-it-off after the voltage at said output node is at, close to, or greater than, the voltage applied to the first power terminal and for turning-it-on after the voltage at said output node is at, or close to, the voltage at the second power terminal.
