[en] Described is a shaper on integrated microcircuits with 100 MHz fast response, in which any limitations for maximum duration of input pulses are eliminated. Given is the principal design of the shaper, in which a microcircuit being a trigger of the D Master-Slave type is used for time coupling to a leading and trailing edge of the input pulse. The microcircuit mode is set in such a way, that on entering the leading edge of the input pulse the Slave section operates at first, and then on entering the trailing edge of the input pulse, the Master section operates. This permits to couple in time logic transitions at the trigger output to the leading edge of the input pulse. Minimum duration of the input pulses with respect to the base is 7 ns. The parameters of the output pulses correspond to the NIM standard and their duration can be set from 7 to 500 ns. The maximum number of outputs of direct or reverse polarities equals 6. Continuous operation of 168 shapers over a month has shown their high reliability; no failure was noted
