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 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 IW4093BN Plastic IW4093BD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs PIN 14 =VCC PIN 7 = GND 142 Output A B Y L L H L H H H L H H H L IW4093B 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. 143 IW4093B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Symbol VT+min VT+max VT-min VT-max VHmin Note VHmax Note IIN 144 Parameter Minimum PositiveGoing Input Threshold Voltage Maximum PositiveGoing Input Threshold Voltage Minimum NegativeGoing Input Threshold Voltage Maximum NegativeGoing Input Threshold Voltage Minimum Hysteresis Voltage Maximum Hysteresis Voltage Maximum Input Leakage Current Guaranteed Limit V ≥-55°C 25°C ≤125 °C Unit Input on terminals A or B; other inputs to VCC 5.0 10 15 2.2 4.6 6.8 2.2 4.6 6.8 2.2 4.6 6.8 V Input on terminals A and B; other inputs to VCC 5.0 10 15 2.6 5.6 6.3 2.6 5.6 6.3 2.6 5.6 6.3 Input on terminals A or B; other inputs to VCC 5.0 10 15 3.6 7.1 10.8 3.6 7.1 10.8 3.6 7.1 10.8 Input on terminals A and B; other inputs to VCC 5.0 10 15 4 8.2 12.7 4 8.2 12.7 4 8.2 12.7 Input on terminals A or B; other inputs to VCC 5.0 10 15 0.9 2.5 4 0.9 2.5 4 0.9 2.5 4 Input on terminals A and B; other inputs to VCC 5.0 10 15 1.4 3.4 4.8 1.4 3.4 4.8 1.4 3.4 4.8 Input on terminals A or B; other inputs to VCC 5.0 10 15 2.8 5.2 7.4 2.8 5.2 7.4 2.8 5.2 7.4 Input on terminals A and B; other inputs to VCC 5.0 10 15 3.2 6.6 9.6 3.2 6.6 9.6 3.2 6.6 9.6 Input on terminals A or B; other inputs to VCC 5.0 10 15 0.3 1.2 1.6 0.3 1.2 1.6 0.3 1.2 1.6 Input on terminals A and B; other inputs to VCC 5.0 10 15 0.3 1.2 1.6 0.3 1.2 1.6 0.3 1.2 1.6 Input on terminals A or B; other inputs to VCC 5.0 10 15 1.6 3.4 5 1.6 3.4 5 1.6 3.4 5 Input on terminals A and B; other inputs to VCC 5.0 10 15 1.6 3.4 5 1.6 3.4 5 1.6 3.4 5 VIN= GND or VCC 18 ±0.1 ±0.1 ±1.0 Test Conditions V V V V V µA IW4093B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) - continued Guaranteed Limit VCC Symbol Parameter Test Conditions ≥-55°C 25°C ≤125 °C Unit 5.0 10 15 20 1 2 4 20 1 2 4 20 30 60 120 600 µA ICC Maximum Quiescent Supply Current (per Package) 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 -0.64 -1.6 -4.2 -1.6 -0.51 -1.3 -3.4 -1.15 -0.36 -0.9 -2.4 IOH VIN= GND or VCC V mA mA 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= VCC 5.0 10 15 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 V Note.
