TECHNICAL DATA IW4060B 14-Stage Ripple-Carry Binary Counter/Divider and Oscillator High-Voltage Silicon-Gate CMOS The IW4060B consists of an oscillator section and 14 ripple-carry binary counter stages. The oscillator configuration allows design of either RC or crystal oscillator circuits. A RESET input is provided which resets the counter to the all-Q’s state and disables the oscillator. A high level on the RESET line accomplishes the reset function. All counter stages are master-slave flip-flops. The state of the counter is advanced one step in binary order on the negative transition of OSC In (and OSC Out). Schmitt trigger action on the input-pulse line permits unlimited input-pulse 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 IW4060BN Plastic IW4060BD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Osc In PIN 16=VCC PIN 8= GND X Outputs Reset Q L No change L Advance to next state H All Outputs are low X = don’t care 115 IW4060B 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 be left open. 116 IW4060B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Guaranteed Limit V ≥-55°C 25°C ≤125 °C Unit VOUT= 0.5 V or VCC - 0.5V VOUT= 1.0 V or VCC - 1.0 V VOUT= 1.5 V VCC - 1.5V 5.0 10 15 3.5 7 11 3.5 7 11 3.5 7 11 V VIL Maximum Low -Level VOUT= 0.5 V or VCC - 0.5V Input Voltage VOUT= 1.0 V or VCC - 1.0 V VOUT= 1.5 V VCC - 1.5V 5.0 10 15 1.5 3 4 1.5 3 4 1.5 3 4 V VOH Minimum High-Level Output Voltage VIN=GND or VCC 5.0 10 15 4.95 9.95 14.95 4.95 9.95 14.95 4.95 9.95 14.95 V VOL Maximum Low-Level Output Voltage VIN=GND or VCC 5.0 10 15 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 V IIN Maximum Input Leakage Current VIN= GND or VCC 18 ±0.1 ±0.1 ±1.0 µA ICC Maximum Quiescent Supply Current (per Package) VIN= GND or VCC 5.0 10 15 20 5 10 20 100 5 10 20 100 150 300 600 3000 µA IOL Minimum Output Low VIN= GND or VCC (Sink) Current UOL=0.4 V UOL=0.5 V UOL=1.5 V 5.0 10 15 0.64 1.6 4.2 0.51 1.3 3.4 0.36 0.9 2.4 Minimum Output VIN= GND or VCC High (Source) Current UOH=2.5 V UOH=4.6 V UOH=9.5 V UOH=13.5 V 5.0 5.0 10 15 -2 -0.64 -1.6 -4.2 -1.6 -0.51 -1.3 -3.4 -1.15 -0.36 -0.9 -2.4 Symbol Parameter VIH Minimum High-Level Input Voltage IOH Test Conditions mA mA 117 IW4060B AC ELECTRICAL CHARACTERISTICS(CL=50pF, RL=200kΩ, Input tr=tf=20 ns) Guaranteed Limit VCC V ≥-55°C 25°C ≤125°C Unit Maximum Clock Frequency (50% Duty Cycle) (Figure 1) 5.0 10 15 3.5 8 12 3.5 8 12 1.75 4 6 MHz tPHL, tPLH Maximum Propagation Delay, Clock to Q4 (Figure 1) 5.0 10 15 740 300 200 740 300 200 1480 600 400 ns tPHL, tPLH Maximum Propagation Delay, Qn to Qn+1 (Figure 2) 5.0 10 15 200 100 80 200 100 80 400 200 160 ns tPHL Maximum Propagation Delay, Reset to Any Q (Figure 3) 5.0 10 15 360 160 100 360 160 100 720 320 200 ns tTHL, tTLH Maximum Output Transition Time, Any Output (Figure 1) 5.0 10 15 200 100 80 200 100 80 400 200 160 ns Symbol fmax CIN Parameter Maximum Input Capacitance - 7.5 pF TIMING REQUIREMENTS(CL=50pF, RL=200 kΩ, Input tr=tf=20 ns) Guaranteed Limit VCC Symbol V ≥-55°C 25°C ≤125°C Unit tw Minimum Pulse Width, Clock (Figure 1) 5.0 10 15 100 40 30 100 40 30 200 80 60 ns tw Minimum Pulse Width, Reset (Figure 3) 5.0 10 15 120 60 40 120 60 40 240 120 80 ns Maximum Input Rise and Fall Times (Figure 1) 5.0 10 15 tf, tr 118 Parameter ns Unlimited IW4060B Figure 1.
