TC4040B 12 Stage Ripple-Carry Binary Counter/Dividers
TC4040B is 12 stage ripple carry binary counter having asynchronous clear function. This counter advances its counting stage by falling edge of CLOCK input. When RESET input is placed “H”, all the circuits are reset regardless of CLOCK input making all the outputs (Q1 through Q12) to be “L”.
This is most suitable for frequency dividers, control circuits and timing circuits.
