H03K 23/58

Gating or clocking signals not applied to all stages, i.e. asynchronous counters (H03K23/74 - H03K23/84 take precedence)

Introduced: January 1985

Title

Titles differ between systems:

IPC: Gating or clocking signals not applied to all stages, i.e. asynchronous counters

CPC: Gating or clocking signals not applied to all stages, i.e. asynchronous counters (H03K23/74 - H03K23/84 take precedence)

Full Title

Full titles differ between systems:

IPC:

Pulse counters comprising counting chains; Frequency dividers comprising counting chains > Gating or clocking signals not applied to all stages, i.e. asynchronous counters

CPC:

Pulse counters comprising counting chains; Frequency dividers comprising counting chains (H03K29/00 takes precedence) > Gating or clocking signals not applied to all stages, i.e. asynchronous counters (H03K23/74 - H03K23/84 take precedence)

Of 4 combined children, 2 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1985.
