The document describes the TC4040BP, TC4040BF, and TC4040BFN devices as 12-stage ripple-carry binary counters with an asynchronous clear function. These CMOS integrated circuits advance their counting stage on the falling edge of the CLOCK input and reset all outputs to 'L' when the RESET input is high.
All outputs (Q1 through Q12) are reset to 'L' regardless of the CLOCK input.
The counter advances its counting stage on the falling edge of the CLOCK input.
