Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute−maximum−rated conditions is not implied. †Derating — SOIC Packages: – 7 mW/_C from 65_ to 125_C TSSOP Package: − 6.1 mW/_C from 65_ to 125_C RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit VCC DC Supply Voltage 2.0 5.5 V Vin DC Input Voltage 0 5.5 V Vout DC Output Voltage 0 VCC V TA Operating Temperature − 40 + 85 _C tr, tf Input Rise and Fall Time VCC = 3.3V ±0.3V VCC =5.0V ±0.5V 0 0 100 20 ns/V DC ELECTRICAL CHARACTERISTICS Symbol Parameter Test Conditions VCC V TA = 25°C TA = − 40 to 85°C Unit Min Typ Max Min Max VIH Minimum High−Level Input Voltage 2.0 3.0 to 5.5 1.50 VCC x 0.7 1.50 VCC x 0.7 V VIL Maximum Low−Level Input Voltage 2.0 3.0 to 5.5 0.50 VCC x 0.3 0.50 VCC x 0.3 V VOH Minimum High−Level Output Voltage Vin = VIH or VIL IOH = − 50μA 2.0 3.0 4.5 1.9 2.9 4.4 2.0 3.0 4.5 1.9 2.9 4.4 V Vin = VIH or VIL IOH = − 4mA IOH = − 8mA 3.0 4.5 2.58 3.94 2.48 3.80 VOL Maximum Low−Level Output Voltage Vin = VIH or VIL IOL = 50μA 2.0 3.0 4.5 0.0 0.0 0.0 0.1 0.1 0.1 0.1 0.1 0.1 V Vin = VIH or VIL IOL = 4mA IOL = 8mA 3.0 4.5 0.36 0.36 0.44 0.44 Iin Maximum Input Leakage Current Vin = 5.5 V or GND (DIR, OE) 0 to 5.5 ± 0.1 ± 1.0 μA This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance cir- cuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v 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. |
