SHIFT REGISTER Russian patent published in 1998 - IPC

FIELD: pulse equipment, computer engineering, control circuits. SUBSTANCE: device has D flip-flops 1-4, clock bus 11, input bus 12, output bus 13. Two-channel multiplexer 5, RC gates 6-9, inverter 10 and new functional connections are introduced to accomplish the goal of invention. D flip-flops 1-4 are designed as single-step flip-flops which are clocked by level. This results in possibility to input information characters into register and to shift them only threshold check of duration of information characters at inputs of shift register bits and shift pulses. Current states of register are stored in level-clocked D flip-flops and capacitors of RC gates which state is kept using feedback circuits. EFFECT: increased stability to noise. 1 dwg
