The device works as follows. . To output the information of the output word, the K-bit address signal is fed to the input of the decoder 1, after the leading edge of this signal, block 2 receives a control signal Shift resolution to receive the output information of the output word by the sequential code. According to the address signal, a signal appears at the corresponding output of the decoder 1 and is fed to the first inputs of the And 7 elements of the corresponding word. After the arrival of the serial code of the output word, the control signal follows. After being received in register 3 by the slacker code of the output relay word, the signals of each relay word appear at its outputs, and through amplifiers 4 arrive at the inputs of D-flip-flops 9 of all bits of the output relay words. Next comes the control signal. The end of a word arrives at the second inputs of the A-7 electronic terminals. This turns on the key 8 of the corresponding word (for example, the first one) and sends a signal to the input from the flip-flops 9 corresponding words, the output relay is written to this signal. The information is triggered into the triggers of the corresponding relay word and its output (or confirmation to block 5. The information of the subsequent output word is generated anchored. But the address of another word is sent to the input of the decoder after the transmission of the signal K The key ends with key 8 associated with the corresponding output of the decoder and sends a signal to the C-flip-flop inputs of another word. The OR 6 element expands the cyclogram of each word's reception. Thus, the useful effect of the device increases the throughput. And 7, the key 8, the trigger 9, which, in comparison with the known devices, allows to achieve a reduction in equipment with an increase in the number of relay words output.
