SL4020B 14 Stage Ripple-Carry Binary Counter/Divider High-Voltage Silicon-Gate CMOS The SL4020B 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 packagetemperature 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 ORDERING INFORMATION SL4020BN Plastic SL4020BD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs Clock PIN 16 =VCC PIN 8 = GND X Output Reset Output state L No change L Advance to next state H All Outputs are low X=don’t care SLS System Logic Semiconductor SL4020B MAXIMUM RATINGS * Symbol Parameter Value Unit -0.5 to +20 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V VOUT IIN DC Input Current, per Pin ±10 mA PD Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ 750 500 mW PD Power Dissipation per Output Transistor 100 mW -65 to +150 °C 260 °C Tstg TL Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) * Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must b e left open.
