H03K3/286 - CPC Classification

Classification description:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits; Generators characterised by the type of circuit or by the means used for producing pulses by the use, as active elements, of bipolar transistors with internal or external positive feedback 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

Sub-classes:

H03K3/2865 » {ensuring a predetermined initial state when the supply voltage has been applied; storing the actual state when the supply voltage fails } 3
H03K3/287 » using additional transistors in the feedback circuit 1
H03K3/288 » using additional transistors in the input circuit 10
H03K3/289 » of the master-slave type 23
H03K3/2893 » Bistables with hysteresis, e.g. Schmitt trigger 7
