SU1244790A1 - Multistable flip-flop - Google Patents

Abstract

The invention relates to a pulse technique and can be used in the construction of technical means in this field. The purpose of the invention is enhanced functionality by reducing inter-element links and increasing the phasing of a multistable trigger. To do this, a threshold element 2 is introduced into the multistable trigger. The trigger also contains input rails and three triggers 1-1 - 1-3. The trigger / to which the input 1-pulse arrives is energized and remains in this state even at the end of the incoming pulse. In this case, the multistable trigger enters a new state and is ready for registration of the next signal. As the threshold level of element 2 increases, the phase of the multistable trigger increases. 1 il. i (L co

multistable trigger.

The drawing shows a structural scheme of a multistable trigger.

The drawing shows the triggers - the threshold element 2 and the input pshny -. The input buses are connected respectively to the installation inputs in 1 flip-flops, the installation inputs in About are connected to the output of the threshold element 2, whose inputs are connected to the direct outputs of the flip-flops -.

The device works as follows.

Suppose, for example, threshold element 2 has a threshold equal to two, one of the triggers is in a single state, and input pulses on buses are missing. In this case, there is no active potential from the output of element 2 for the inputs of the installation in O triggers.

When it arrives from one of the buses 3 1 to the input of the installation into 1 of one of the triggers 1 1 -, which is in the initial zero state, an input pulse arrives. This trigger is energized and, therefore, at this moment in time there are two triggers in the excited state. As a result, the output of the threshold element 2 is set to

inverse to the source and the inputs; Triggers receive an active signal. The trigger, which was previously in the excited state, is set to its original, but just that, condition; the device is set to zero. At the same time, the threshold logic element is set, in the state corresponding to the initial one and at the inputs of the installation in the O flip-flops the active signal is removed. The trigger, which the input pulse continues to receive, is again excited: it waits and remains in this state and upon termination of the input signal. Thus, the device records the pulse, i.e. his signal.

As the threshold of the threshold element 2 increases, the phase of the multistable trigger increases.
