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. All voltages are with respect to ground unless otherwise specified. 2. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 3. VI and VO are used to denote specific conditions for VI/O. 4. II and IO are used to denote specific conditions for II/O. 5. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 6) MIN MAX UNIT VCC Supply voltage 2.3 3.6 V VIH High-level control input voltage VCC = 2.3 V to 2.7 V 1.7 5.5 V VIH High-level control input voltage VCC = 2.7 V to 3.6 V 2 5.5 V VIL Low-level control input voltage VCC = 2.3 V to 2.7 V 0 0.7 V VIL Low-level control input voltage VCC = 2.7 V to 3.6 V 0 0.8 V VI/O Data input/output voltage 0 5.5 V TA Operating free-air temperature −40 85 °C NOTE 6: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation.
