KK4020B

www.DataSheet4U.com 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 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. 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 16 1 16 1 N SUFFIX PLASTIC DIP ORDERING INFORMATION KK4020BN Plastic DIP KK4020BD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM 9 7 5 CLOCK 10 4 6 13 12 14 15 1 2 3 11 RESET Q1 Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11 Q12 Q13 Q14 PIN ASSIGNMENT FUNCTION TABLE Inputs Clock Reset L L X H= high level L = low level X=don’t care Output Output state No change Advance to next state All Outputs are low PIN 16 =VCC PIN 8 = GND H 1 www.DataSheet4U.com KK4020B MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN PD Ptot Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Power Dissipation per Output Transisto...
