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) VI and VO are used to denote specific conditions for VI/O. (5) The package thermal impedance is calculated in accordance with JESD 51-7. (6) The package thermal impedance is calculated in accordance with JESD 51-5. MIN MAX UNIT VCC Supply voltage 2.3 3.6 V VCC = 2.3 V to 2.7 V 1.7 5.5 VIH High-level control input voltage V VCC = 2.7 V to 3.6 V 2 5.5 VCC = 2.3 V to 2.7 V 0 0.7 VIL Low-level control input voltage V VCC = 2.7 V to 3.6 V 0 0.8 VI/O Data input/output voltage 0 5.5 V TA Operating free-air temperature –40 85 °C (1) All unused control inputs of the device must be held at VCC or GND to ensure proper device operation.
