using bi-stable regenerative trigger circuits (H03K23/42 - H03K23/48 take precedence)

Introduced: January 1985

Title

Titles differ between systems:

IPC: using bi-stable regenerative trigger circuits

CPC: using bi-stable regenerative trigger circuits (H03K23/42 - H03K23/48 take precedence)

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 > using bi-stable regenerative trigger circuits

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 > using bi-stable regenerative trigger circuits (H03K23/42 - H03K23/48 take precedence)

Of 4 combined children, 3 exist in both systems.

1 codes are CPC-only extensions.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1985.
