H03K 23/42

Out-of-phase gating or clocking signals applied to counter stages

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 > Out-of-phase gating or clocking signals applied to counter stages

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 > Out-of-phase gating or clocking signals applied to counter stages

Of 3 combined children, 2 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 1985.
