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) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. (3) The value of VCC is provided in the recommended operating conditions table. (4) The package thermal impedance is calculated in accordance with JESD 51-7. MIN MAX UNIT Operating 1.65 3.6 VCC Supply voltage V Data retention only 1.5 VCC = 1.65 V to 1.95 V 0.65 × V CC VIH High-level input voltage VCC = 2.3 V to 2.7 V 1.7 V VCC = 2.7 V to 3.6 V 2 VCC = 1.65 V to 1.95 V 0.35 × V CC VIL Low-level input voltage VCC = 2.3 V to 2.7 V 0.7 V VCC = 2.7 V to 3.6 V 0.8 VI Input voltage 0 5.5 V High or low state 0 VCC VO Output voltage V 3-state 0 5.5 VCC = 1.65 V –4 VCC = 2.3 V –8 IOH High-level output current mA VCC = 2.7 V –12 VCC = 3 V –24 VCC = 1.65 V 4 VCC = 2.3 V 8 IOL Low-level output current mA VCC = 2.7 V 12 VCC = 3 V 24 ∆t/∆v Input transition rise or fall rate 10 ns/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.
