H03K 19/02 using specified components (, H03K19/003 - H03K19/0175 take precedence)
Introduced: September 1968
Title
Titles differ between systems:
IPC: using specified components
CPC: using specified components (, H03K19/003 - H03K19/0175 take precedence)
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
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)
IPC and CPC are identically structured here. All 11 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
