нагрузок, однако режим работы нагрузок в подобных устройствах остаетс фиксированным. Вместе с тем, если уровень напр жений и токов в нагрузках может быть уменьшен в процессе работы без нарушени их нормального функционировани , то использование известных многоканаль-ных коммутаторов ведет к нерациона10 льному потреблению мощности устройства . Кроме того, при использовании нагрузок Определенного вида, в частности индикаторных приборов или сигнальных лампочек, возможность loads, however, the operation mode of the loads in such devices remains fixed. However, if the level of voltages and currents in loads can be reduced during operation without disrupting their normal functioning, the use of known multi-channel switches leads to an inefficient power consumption of the device. In addition, when using loads of a certain type, in particular indicator devices or signal lights,

Claims

There are 30 naps, two I elements are introduced into each channel, and two switching and two control inputs are connected to the key elements, the switching elements of the key elements are connected to the corresponding load supply busbars, the first control input of the key element of each channel is connected to the output of the first AND element. The first input of which is connected to an inverse output of the trigger of this channel, the second input is connected to the inverse output of the trigger of the next channel, the second control input of the key element is connected to the output of the second element The first input of which is connected to the noninverted O house trigger the channel, and the second - with the noninverted output of the flip-flop of the next channel. The drawing shows a diagram of the proposed device. The multi-channel switch of functional loads contains in each i-M channel i 1, 2,. . . , n trigger 1, elements AND 2, 3 and key element 4, at the output of which load 5 is turned on. Bus power supply buses 6 and 7 are connected to the corresponding switched inputs of key elements 4, information buses 8 and 9 serve to control the state of channels, clock the pulses are supplied to bus 10. The voltage, current or duty cycle of the pulses fed to bus 7 is higher than bus 6. The key elements 4 connect loads 5 to bus 7 when there is a signal 1 at the output of the element 2, and bus b when the output signal elenalicii ment And 3. To eliminate the possibility The termination of buses B and 7 power through key elements 4 last MUST provide isolation between buses B and 7, which can be achieved, for example, by using split diodes or using as key elements 4 schemes excluding the possibility of an on state in both channels at the same time. The operation of the proposed switch is carried out as follows. Suppose, in the initial state, all the triggers 1 are in the zero state, i.e. in the state when on their non-inverse outputs it has a signal O and in the inverse signal 1. Load 5 is de-energized, because the outputs of elements I 2 3 have O signals. If there is a signal 1 on bus 8, a signal O on bus 9 and the clock and pulse on the bus 10, the trigger 1 of the first channel goes into one state. At the same time, the signal 1 and the key element 4 connect the load 5 to the bus 7 at the output of the AND element of this channel. When the second clock pulse arrives on the bus 10, the triggers 1 of the first and second channels go into one state, resulting in a signal . appears at the output of the element And 3 of the first channel and element 2 of the second channel. Accordingly, the load 5 of the first channel is connected to the bus 6, and the load 5 of the second channel is connected to the bus 7. Similarly, when the third clock pulse arrives on the bus 10, the load 5 of the first channel is connected to the bus b, and the load 5 of the second channel to the bus 7. Similarly, when the third clock pulse arrives on the bus 10, the loads 5 of the first and second channels are connected to the bus b, and the load 5 of the third channel to the bus 7. Thus, when sequentially recording information in trigger 1, the load 5 after him than the others included the channel would operate in an active mode. Thus, in the proposed switchboard, by introducing new elements and making connections between all the elements, it became possible to vary the operating mode of the loads — to connect the display elements to sources of different voltages. A multi-channel switch of functional loads, containing in each channel a trigger and a key element whose output is connected to a load, and a switched input with a power supply bus for loads, triggers are combined into a shift register, characterized in that A second power supply bus was introduced, two I elements were inserted into each channel, and the key elements had two switching and two control inputs, the switching inputs of the key elements were connected corresponding power supply busses, the first control input of the key element of each channel is connected to the output of the first element I, the first input of which is connected to the non-inverted trigger output of this channel, the second input is connected to the inverse output of the next channel trigger, the second control input of the key element is connected to the output the second element H, the first input of which is connected to the non-inverted trigger output of this channel, and the second to the non-inverted trigger output of the next channel.
