| TECHNICAL DATA IW4518B Dual Up-Counter High-Voltage Silicon-Gate CMOS The IW4518B Dual BCD Up-Counter consists two identical, internally synchronous 4-stage counters. The counter stages are D-type flip-flops having interchangeable CLOCK and ENABLE lines for incrementing on either the positive-going or negative-going transition. For single-unit operation the ENABLE input is maintained high and the counter advances on each positive-going transition of the CLOCK. The counters are cleared by high levels on their RESET lines. The counter can be cascaded in the ripple mode by connecting Q4 to the enable input of the subsequent counter while the CLOCK input of the latter is held low. * Operating Voltage Range: 3.0 to 18 V * Maximum input current of 1 A at 18 V over full packagetemperature range; 100 nA at 18 V and 25C * 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 IW4518BN Plastic IW4518BD SOIC TA = -55 to 125 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs CLOCK ENABLE RESET H L PIN 16=VCC PIN 8= GND X X L H X X X = don't care L L L L L L H Outputs Mode Increment Counter Increment Counter No Change No Change No Change No Change Q1 thru Q4=L 163 IW4518B MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN PD PD 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 Transistor Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +20 -0.5 to VCC +0.5 -0.5 to VCC +0.5 10 750 500 100 -65 to +150 260 Unit V V V mA mW mW C C 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. 164 IW4518B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Symbol VIH Parameter Minimum High-Level Input Voltage Test Conditions VOUT= 0.5 V or VCC - 0.5V VOUT= 1.0 V or VCC - 1.0 V VOUT= 1.5 V or VCC - 1.5V V 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 18 5.0 10 15 20 5.0 10 15 5.0 5.0 10 15 Guaranteed Limit -55C 3.5 7 11 1.5 3 4 4.95 9.95 14.95 0.05 0.05 0.05 0.1 5 10 20 100 0.64 1.6 4.2 -2 -0.64 -1.6 -4.2 25C 3.5 7 11 1.5 3 4 4.95 9.95 14.95 0.05 0.05 0.05 0.1 5 10 20 100 0.51 1.3 3.4 -1.6 -0.51 -1.3 -3.4 125 C 3.5 7 11 1.5 3 4 4.95 9.95 14.95 0.05 0.05 0.05 1.0 150 300 600 3000 0.36 0.9 2.4 mA -1.15 -0.36 -0.9 -2.4 Unit 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 or VCC - 1.5V Minimum High-Level Output Voltage Maximum Low-Level Output Voltage Maximum Input Leakage Current Maximum Quiescent Supply Current (per Package) VIN=GND or VCC V VOH V VOL VIN=GND or VCC V IIN ICC VIN= GND or VCC VIN= GND or VCC A A IOL Minimum Output Low VIN= GND or VCC (Sink) Current UOL=0.4 V UOL=0.5 V UOL=1.5 V 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 mA IOH 165 IW4518B AC ELECTRICAL CHARACTERISTICS(CL=50pF, RL=200k, Input tr=tf=20 ns) VCC Symbol fmax Parameter Maximum Clock Frequency, (Figure 1) V 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 1.5 3 4 560 230 160 650 225 170 200 100 80 Guaranteed Limit -55C 25C 1.5 3 4 560 230 160 650 225 170 200 100 80 7.5 125C 0.75 1.5 2 1120 460 320 1300 450 340 400 200 160 Unit MHz tPHL, tPLH Maximum Propagation Delay, Clock or Enable to Output (Figures 1,3) Maximum Propagation Delay, Reset to Output (Figure 2) Maximum Output Transition Time, Any Output (Figure 1) Maximum Input Capacitance ns tPHL ns tTHL, tTLH ns CIN pF TIMING REQUIREMENTS(CL=50pF, RL=200 k, Input tr=tf=20 ns) VCC Symbol tw Parameter Minimum Pulse Width, Clock (Figure 1) V 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 200 100 70 250 110 80 400 200 140 15 5 5 Guaranteed Limit -55C 25C 200 100 70 250 110 80 400 200 140 15 5 5 125C 400 200 140 500 220 160 800 400 280 15 5 5 Unit ns tw Minimum Pulse Width, Reset (Figure 2) ns tw Minimum Pulse Width, Enable (Figure 3) ns tr, tf Maximum Input Rise and Fall Times (Figure 1) s Figure 1.
