KK4040B
12-Stage Binary Ripple Counter
High-
Voltage Silicon-Gate
CMOS
The KK4040B is ripple-carry binary counter.
All counter stages are masterslave 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.
