These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7 recommended operating conditions (see Note 3) MIN MAX UNIT VCC Supply voltage 4.5 5.5 V VIH High-level input voltage 2 V VIL Low-level input voltage 0.8 V VI Input voltage 0 5.5 V VO Output voltage 0 VCC V IOH High-level output current −8 mA IOL Low-level output current 8 mA TA Operating free-air temperature I-suffix device −40 85 °C TA Operating free-air temperature Q-suffix device −40 125 °C NOTE 3: All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. |
