Full Title

Full titles differ between systems:

IPC:

Logic circuits, i.e. having at least two inputs acting on one output; Inverting circuits > using specified components > using semiconductor devices > using thyristors

CPC:

Logic circuits, i.e. having at least two inputs acting on one output (circuits for computer systems using fuzzy logic G06N7/02); Inverting circuits > using specified components (, H03K19/003 - H03K19/0175 take precedence) > using semiconductor devices (H03K19/173 takes precedence; wherein the semiconductor devices are only diode rectifiers H03K19/12) > using thyristors

No child classifications to compare. This is a leaf node in both IPC and CPC.
