bistable

Full Title

Circuits for generating electric pulses; Monostable, bistable or multistable circuits (H03K4/00 takes precedence; for digital function generators in computers G06F1/02) > Generators characterised by the type of circuit or by the means used for producing pulses (H03K3/64 - H03K3/84 take precedence) > by the use, as active elements, of bipolar transistors with internal or external positive feedback (H03K3/023, H03K3/027 take precedence) > using means other than a transformer for feedback > using at least two transistors so coupled that the input of one is derived from the output of another, e.g. multivibrator > bistable
