TECHNICAL DATA IW4502B Strobed Hex Inverter/Buffer High-Voltage Silicon-Gate CMOS The IW4502B consists of six inverter/buffers with 3-state outputs. A logic “1” on the OUTPUT ENABLE input produces a high impedance state in all six outputs. This feature permits common busing of the outputs, thus simplifying system design. A logic “1” on the DIRECTION input switches all six outputs to logic “0” if the OUTPUT ENABLE input is a logic “0”. • 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 IW4502BN Plastic IW4502BD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 16=VCC PIN 8= GND Output Output Enable Direction A Y L L L H L L H L L H X L H X X Z Z = high impedance X = don’t care 147 IW4502B 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. 148 IW4502B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Guaranteed Limit V ≥-55°C 25°C ≤125 °C Unit 5.0 10 15 3.5 7 11 3.5 7 11 3.5 7 11 V Maximum Low -Level VOUT= VCC - 0.5V Input Voltage VOUT= VCC - 1.0 V VOUT= 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 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 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 1 2 4 20 1 2 4 20 30 60 120 600 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 3.84 9.6 25.2 3.06 7.8 20.4 2.16 5.4 14.4 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 18 ±0.4 ±0.4 ±12 Symbol Parameter VIH Minimum High-Level Input Voltage VIL IOH IOZ Maximum Tree-State Leakage Current Test Conditions VOUT=0.5 V VOUT=1 V VOUT=1.5 Output in High-Impedance State VIN= GND or VCC VOUT= GND or VCC mA mA µA 149 IW4502B AC ELECTRICAL CHARACTERISTICS(CL=50pF, RL=200kΩ unless otherwise specified, Input tr=tf=20 ns) Guaranteed Limit VCC Symbol Parameter V ≥-55°C 25°C ≤125°C Unit tPHL Maximum Propagation Delay, Input A or Direction to Output Y (Figure 1) 5.0 10 15 270 120 80 270 120 80 540 240 160 ns tPLH Maximum Propagation Delay, Input A or Direction to Output Y (Figure 1) 5.0 10 15 380 180 130 380 180 130 760 360 260 ns tPHZ Maximum Propagation Delay, Output Enable to Output Y (Figure 2) RL = 1 kΩ 5.0 10 15 120 80 60 120 80 60 240 160 120 ns tPZH Maximum Propagation Delay, Output Enable to Output Y (Figure 2) RL = 1 kΩ 5.0 10 15 220 100 80 220 100 80 440 200 160 ns tPLZ Maximum Propagation Delay, Output Enable to Output Y (Figure 2) RL = 1 kΩ 5.0 10 15 250 130 110 250 130 110 500 260 220 ns tPZL Maximum Propagation Delay, Output Enable to Output Y (Figure 2) RL = 1 kΩ 5.0 10 15 250 110 80 250 110 80 500 220 160 ns tTLH Maximum Output Transition Time, Any Output (Figure 1) 5.0 10 15 200 100 80 200 100 80 400 200 160 ns tTHL Maximum Output Transition Time, Any Output (Figure 1) 5.0 10 15 120 60 40 120 60 40 240 120 80 ns CIN Maximum Input Capacitance - 7.5 pF Maximum Tree-State Output Capacitance (Output in High-Impedance State) - 15 pF COUT 150 IW4502B Figure 1.
