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.
