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. (2) All voltages are with respect to ground, unless otherwise specified. (3) The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. (4) This value is limited to 5.5 V maximum. (5) The package thermal impedance is calculated in accordance with JESD 51-7. Recommended Operating Conditions (1) MIN MAX UNIT VCC Supply voltage 1.65 5.5 V VI/O I/O port voltage 0 VCC V VCC = 1.65 V to 1.95 V VCC × 0.65 VCC = 2.3 V to 2.7 V VCC × 0.7 VIH High-level input voltage, control input V VCC = 3 V to 3.6 V VCC × 0.7 VCC = 4.5 V to 5.5 V VCC × 0.7 VCC = 1.65 V to 1.95 V VCC × 0.35 VCC = 2.3 V to 2.7 V VCC × 0.3 VIL Low-level input voltage, control input V VCC = 3 V to 3.6 V VCC × 0.3 VCC = 4.5 V to 5.5 V VCC × 0.3 VI Control input voltage 0 5.5 V VCC = 1.65 V to 1.95 V 20 VCC = 2.3 V to 2.7 V 20 Δt/Δv Input transition rise/fall time ns/V VCC = 3 V to 3.6 V 10 VCC = 4.5 V to 5.5 V 10 TA Operating free-air temperature –40 85 °C (1) 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.
