TECHNICAL DATA
KK4020B
14 Stage Ripple-Carry Binary
Counter/Divider
High-Voltage Silicon-Gate CMOS
The KK4020B 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.
• Operating Voltage Range: 3.0 to 18 V
• Maximum input current of 1 µA at 18 V over full package-temperature
range; 100 nA at 18 V and 25°C
• Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply
