pulse equipment. SUBSTANCE: flip-flop device incorporates flip-flop 1 which set and reset inputs are connected through correspondingly first 6 and second 7 resistors to common bus, first 2 and second 6 OR ELSE gates whose first inputs are connected to input bus 10, whose second inputs are linked correspondingly to forward and inverse output of flip-flop 1 and whose outputs are connected to plates of correspondingly first 4 and second 5 capacitors, third 8 and fourth 9 resistors placed between second plates of correspondingly first 4 and second 5 capacitors and set and reset inputs flip-flop 1. Resistance Rd of third 8 and fourth 9 resistors is chosen from condition , where Ro is resistance of first 6 and second 7 resistors; Umax is maximum value of operation threshold of logic gates of flip-flop 1; E is supply voltage. EFFECT: increased supply noise immunity. 1 dwg
