TECHNICAL DATA
KK4040B
12-Stage Binary Ripple Counter
High-Voltage Silicon-Gate CMOS
The
KK4040B
is 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 state. Schmitt trigger action on the input-pulse line permits
unlimited rise and fall times.
