Gating or clocking signals applied to all stages, i.e. synchronous counters

Introduced: January 1985

Full Title

Full titles differ between systems:

IPC:

Pulse counters comprising counting chains; Frequency dividers comprising counting chains > Gating or clocking signals applied to all stages, i.e. synchronous counters

CPC:

Pulse counters comprising counting chains; Frequency dividers comprising counting chains (H03K29/00 takes precedence) > Gating or clocking signals applied to all stages, i.e. synchronous counters

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1985.
