A retriggable multivibrator is disclosed which comprises a first delay circuit (3) connected for delaying an input signal a predetermined time, a second delay circuit (5) connected to receive an output of the first delay circuit and having a set or a rest function, a flip-flop circuit (2) connected to be set or reset in accordance with an input signal and output signal which comes from the second delay circuit (5) and control circuit (6) connected to detect a reentry of an input signal within a predetermined delay time of the first and second delay circuits and to set or reset the second delay circuit.
摘要:
A circuit which responds to the application of a pulse to its input (6) by generating a pulse at its output (3), the output pulse having a minimum duration T and being extended by the remaining length of the input pulse should the input pulse be still present at the end of the time T, comprises a pair of semiconductor switches (1,2) connecting the output (3) to points (5,4) carrying respective logic levels. The input pulse closes the first switch (1) and also inhibits a gate circuit (9). The resulting logic level on the output (3) closes the second switch (2) after delay by T in a delay circuit (13) and transmission through the gate circuit (9), thereby restoring the original logic level. The instant when this occurs coincides with the presence of the delayed output pulse at the output (14) of the delay circuit and the absence of the pulse at the arrangement input (6). A hold circuit circuit (15) may be provided for holding the logic level currently present at the output (3). The circuit may be used as an equalisation pulse generator for a data path in a semiconductor memory integrated circuit.
