| TECHNICAL DATA IW4093B Quad 2-Input NAND Schmitt Triggers High-Voltage Silicon-Gate CMOS The IW4093B consists of four Schmitt-trigger circuits. Each circuit functions as a two-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive- and negative- going signals. The difference between the positive voltage (VP) and the negative voltage (VN) is defined as hysteresis voltage (VH) (see Fig.1). * 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 IW4093BN Plastic IW4093BD SOIC TA = -55 to 125 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs A L PIN 14 =VCC PIN 7 = GND L H H B L H L H Output Y H H H L 142 IW4093B 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. 143 IW4093B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Symbol VT+min Parameter Minimum PositiveGoing Input Threshold Voltage Test Conditions Input on terminals A or B; other inputs to VCC Input on terminals A and B; other inputs to VCC VT+max Maximum PositiveGoing Input Threshold Voltage Input on terminals A or B; other inputs to VCC Input on terminals A and B; other inputs to VCC VT-min Minimum NegativeGoing Input Threshold Voltage Input on terminals A or B; other inputs to VCC Input on terminals A and B; other inputs to VCC VT-max Maximum NegativeGoing Input Threshold Voltage Input on terminals A or B; other inputs to VCC Input on terminals A and B; other inputs to VCC VHmin Note Minimum Hysteresis Voltage Input on terminals A or B; other inputs to VCC Input on terminals A and B; other inputs to VCC VHmax Note Maximum Hysteresis Voltage Input on terminals A or B; other inputs to VCC Input on terminals A and B; other inputs to VCC IIN Maximum Input Leakage Current VIN= GND or VCC V 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 5.0 10 15 18 Guaranteed Limit -55C 2.2 4.6 6.8 2.6 5.6 6.3 3.6 7.1 10.8 4 8.2 12.7 0.9 2.5 4 1.4 3.4 4.8 2.8 5.2 7.4 3.2 6.6 9.6 0.3 1.2 1.6 0.3 1.2 1.6 1.6 3.4 5 1.6 3.4 5 0.1 25C 2.2 4.6 6.8 2.6 5.6 6.3 3.6 7.1 10.8 4 8.2 12.7 0.9 2.5 4 1.4 3.4 4.8 2.8 5.2 7.4 3.2 6.6 9.6 0.3 1.2 1.6 0.3 1.2 1.6 1.6 3.4 5 1.6 3.4 5 0.1 125 C 2.2 4.6 6.8 2.6 5.6 6.3 3.6 7.1 10.8 4 8.2 12.7 0.9 2.5 4 1.4 3.4 4.8 2.8 5.2 7.4 3.2 6.6 9.6 0.3 1.2 1.6 0.3 1.2 1.6 1.6 3.4 5 1.6 3.4 5 1.0 A V V V V V Unit V 144 IW4093B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) - continued VCC Symbol ICC Parameter Maximum Quiescent Supply Current (per Package) Test Conditions VIN= GND or VCC V 5.0 10 15 20 5.0 10 15 5.0 5.0 10 15 5.0 10 15 5.0 10 15 Guaranteed Limit -55C 1 2 4 20 0.64 1.6 4.2 -2.0 -0.64 -1.6 -4.2 4.95 9.95 14.95 0.05 0.05 0.05 25C 1 2 4 20 0.51 1.3 3.4 -1.6 -0.51 -1.3 -3.4 4.95 9.95 14.95 0.05 0.05 0.05 125 C 30 60 120 600 0.36 0.9 2.4 mA -1.15 -0.36 -0.9 -2.4 4.95 9.95 14.95 0.05 0.05 0.05 V Unit 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 Minimum High-Level Output Voltage Maximum Low-Level Output Voltage VIN=GND or VCC mA IOH VOH VOL VIN= VCC V Note.
