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 negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.. 2. This value is limited to 4.6 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions (see Note 4) MIN MAX UNIT VCC Supply voltage 1.65 3.6 V VCC = 1.65 V to 1.95 V 0.65 × VCC 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 × VCC 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 VCC V VO Output voltage 0 VCC V VCC = 1.65 V –4 IOH High level output current VCC = 2.3 V –12 mA IOH High-level output current VCC = 2.7 V –12 mA VCC = 3 V –24 VCC = 1.65 V 4 IOL Low level output current VCC = 2.3 V 12 mA IOL Low-level output current VCC = 2.7 V 12 mA VCC = 3 V 24 ∆t/∆v Input transition rise or fall rate 10 ns/V TA Operating free-air temperature –40 85 °C NOTE 4: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation.
