00 The invention relates to automation and computing and can be used in asynchronous information exchange devices. A device is known that, in each channel, contains a trigger for receiving information, a trigger, and two EI elements. The device has a enable input, a quench input and a read input ll. The disadvantage of this device is its complexity. The closest to the proposed r to the technical essence is a device for entering information, containing a multiphase pulse generator and in each channel the issuance trigger and the receive trigger connected by single and zero inputs to the corresponding inputs and outputs of the device, clock input and output of the issuing three each channel is connected to the corresponding outputs of a multiphase generator and outputs: devices, and in each channel, the unit and zero inputs of the trigger trigger are connected respectively with the unit and zero outputs trigger The receive channel, while the clock input of the receive trigger is connected to the input of the inverter, the output of which is connected to the first input of the element I, the second input of which is connected to the zero output of the receive trigger, and the output to the input of zeroing of the output trigger. The disadvantage of this device is its complexity . The purpose of the invention is to simplify the device. The above objective is achieved by the fact that a device for inputting information contains a group of flip-flops, the set-up inputs of which are corresponding to the information inputs of the device, a pulse generator, the output of which is connected to the clock input of the first trigger directly and through the inverter the second input of which is connected to the inverting output of the second trigger and to the input of setting the first trigger to zero, the output of the element I is connected to the reset input of the first trigger, the input of which is set to one It is connected to the non-inverting output of the second flip-flop, and the output to the setup input of the second flip-flop, contains a group of elements And the IL element whose inputs are connected to the installation inputs of group triggers, the output connected to the installation input of the second trigger unit, the outputs of group triggers are connected to the first inputs of the elements AND of the group, the second inputs of which are connected to the output of the first trigger, and the outputs of the elements of the AND group are the information outputs of the device and are connected to the clock inputs of the group triggers. The drawing shows a block diagram of the device. The device contains a group of triggers 1, information inputs 2 of the device, a driver 3, a second trigger 4, an inverter 5, element B, a new trigger 7, a pulse generator 8, an element OR 9, a group of elements AND 10 The device works as follows. In the initial position, the triggers 4 and 7 of the imager 3 and the triggers 1 of the channels are in zero proportion. A zero signal from the output of the element 6 is sent to the zeroing input of the trigger 7 of the driver 3. When the information signal arrives at the input 2, the trigger 1 switches to a single state. At the same time, the information signal from input 2 through the OR .9 element transfers the input trigger 4 of the driver 3 to one state, and the zero signal to the trigger 7 stops. A synchronizing pulse from the generator 8 output then triggers 7 to a single state, which then arrives at the clock input trigger, forming the beginning of the output pulse of the actuator 3, thereby triggering 4 on the zero input to zero state. At the end of the pulse from the output of the generator 8, the signal from the element 6 and the trigger 7 switches to the zero state, the signal from the zero input of the trigger 4 is removed, and the driver 3 is ready to receive the next signal. The synchronized pulse from the output of the imaging unit 3 through the element And 10 channels allows the issuance of synchronized information to the output of the device. The output signal on its svot.- to its falling edge is transmitted to the trigger. Hera 1 channels to the zero state and prepares them to receive the following information. The output signals of the device are formed in duration equal to the duration of the clock pulses of the generator 8 using the imaging unit 3 after the asynchronous information has arrived at the inputs. The invention compared to the known device due to the introduction of the OR element and into each channel of the AND element is simpler, since it contains 30–35% less number of elements due to the use of a single-ended pulse generator, simplification of the channel scheme and the use of a synchronized pulse generator of equal duration pulse generator.
