| TECHNICAL DATA IW4050B Hex Buffer/Converter High-Voltage Silicon-Gate CMOS The IW4050B is noninverting hex buffers and feature logic-level conversion using only one supply (voltage (VCC). The input-signal high level (VIH) can exceed the VCC supply voltage when these devices are used for logic-level conversions. These devices are intended for use as CMOS to DTL/TTL converters. * 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 * High-to-low level conversion ORDERING INFORMATION IW4050BN Plastic IW4050BD SOIC TA = -55 to 125 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT NC = NO CONNECTION FUNCTION TABLE Inputs A L PINS 13, 16 = NO CONNECTION PIN 1 =VCC PIN 8 = GND H Output Y L H 93 IW4050B 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 VCC** to +18 -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. 94 IW4050B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Symbol VIH Parameter Minimum High-Level Input Voltage Test Conditions VOUT= VCC - 0.5V VOUT= VCC - 1.0 V VOUT= 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 4.5 5 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 1 2 4 20 3.3 4 10 26 -2.6 -0.81 -2.0 -5.2 25C 3.5 7 11 1.5 3 4 4.95 9.95 14.95 0.05 0.05 0.05 0.1 1 2 4 20 2.6 3.2 8 24 -2.1 -0.65 -1.65 -4.3 125 C 3.5 7 11 1.5 3 4 4.95 9.95 14.95 0.05 0.05 0.05 1.0 30 60 120 600 1.8 2.4 5.6 18 mA -1.55 -0.48 -1.18 -3.1 Unit V VIL Maximum Low -Level VOUT= 0.5V Input Voltage VOUT= 1.0 V VOUT= 1.5V Minimum High-Level Output Voltage Maximum Low-Level Output Voltage Maximum Input Leakage Current Maximum Quiescent Supply Current (per Package) VIN= VCC V VOH V VOL VIN=GND 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=0.4 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 95 IW4050B AC ELECTRICAL CHARACTERISTICS(CL=50pF, RL=200k, Input tr=tf=20 ns) VIN Symbol tPLH Parameter Maximum Propagation Delay, Input A to Output Y (Figure 1) V 5 10 10 15 15 5 10 10 15 15 5 10 15 5 10 15 VCC V 5 10 5 15 5 5 10 5 15 5 5 10 15 5 10 15 Guaranteed Limit -55C 140 80 90 60 80 110 55 100 30 100 160 80 60 60 40 30 25C 140 80 90 60 80 110 55 100 30 100 160 80 60 60 40 30 7.5 125C 280 160 180 120 160 220 110 200 60 200 320 160 120 120 80 60 Unit ns tPHL Maximum Propagation Delay, Input A to Output Y (Figure 1) ns tTLH Maximum Output Transition Time, Any Output (Figure 1) Maximum Output Transition Time, Any Output (Figure 1) Maximum Input Capacitance ns tTHL ns CIN pF Figure 1.
