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.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
