Multistate digital electronic systems and circuits which can adopt several different logic states or levels, and which comprise various level-detector and state-forming circuits, being members or not of an inverter restorer circuit. Multistable static memory wherein diode 2 and transistor 4 form in the same way as diode 3 and transistor 5 two level-detector circuits, and transistor 14 with diode 21 together with transistor 15 and diode 22 form state formers, and feedback 29. The system comprises other alternatives of static memories, in addition to dynamic memory, state detector, converters, comparator, incrementer, counter, summator and arithmetic operator with carrying over, level clamper for telephonic communication, and multistate frequency modulation transmitter-receiver. Applicable in the electronics industry. <IMAGE>
