The HCF4040B is a ripple carry binary counter. All
counter stages are master-slave flip-flops. The
state of a counter advances one count on the
negative transition of each input pulse; a high level
on the RESET line resets the counter to its all
zeros stage. Schmitt trigger action on the input
pulse line permits unlimited clock rise and fall
times.
All inputs and outputs are buffered
