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 voltage ratings may be exceeded if the input and output current ratings are observed. 2. This value is limited to 5.5 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 4) MIN MAX UNIT VCC Supply voltage 2 6 V VCC = 2 V 1.5 High-level input voltage, VCC = 3 V 2.1 VIH High-level input voltage, control inputs VCC = 3.3 V 2.3 V VIH control inputs VCC = 4.5 V 3.15 V VCC = 6 V 4.2 VCC = 2 V 0.5 Low-level input voltage, VCC = 3 V 0.9 VIL Low-level input voltage, control inputs VCC = 3.3 V 1 V VIL control inputs VCC = 4.5 V 1.35 V VCC = 6 V 1.8 VI Control input voltage 0 VCC V VIO Input/output voltage 0 VCC V VCC = 2 V 1000 VCC = 3 V 800 ∆t/∆v Input transition rise or fall time VCC = 3.3 V 700 ns ∆t/∆v Input transition rise or fall time VCC = 4.5 V 500 ns VCC = 6 V 400 TA Operating free-air temperature −40 125 °C NOTE 4: All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
