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 negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions (see Note 3) MIN MAX UNIT VCC Supply voltage 2.3 3.6 V BIASV Bias voltage 1.3 VCC V VIH High level control input voltage VCC = 2.3 V to 2.7 V 1.7 V VIH High-level control input voltage VCC = 2.7 V to 3.6 V 2 V VIL Low level control input voltage VCC = 2.3 V to 2.7 V 0.7 V VIL Low-level control input voltage VCC = 2.7 V to 3.6 V 0.8 V TA Operating free-air temperature –40 85 °C NOTE 3: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation.
