H03K19/215 - CPC Classification

Classification description:

Logic circuits, i.e. having at least two inputs acting on one output ; Inverting circuits characterised by logic function, e.g. AND, OR, NOR, NOT circuits; EXCLUSIVE-OR circuits, i.e. giving output if input signal exists at only one input; COINCIDENCE circuits, i.e. giving output only if all input signals are identical using field-effect transistors
