DIFF Subgroup
H03K 3/01

Details

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits > Details

CPC:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits (H03K4/00 takes precedence; for digital function generators in computers G06F1/02) > Details

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
