TC4020BP/BF/BFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC4020BP,TC4020BF,TC4020BFN TC4020B 14 Stage Ripple-Carry Binary Counter/Dividers TC4020B is 14 stage ripple carry binary counter having asynchronous clear function. The 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, Q4~Q14) to be “L”. This is most suitable for frequency dividers, control circuits and timing circuits. Note: xxxFN (JEDEC SOP) is not available in Japan.
