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: 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 4) TA = 25°C –55 °C to 125 °C –40 °C to 85 °C UNIT MIN MAX MIN MAX MIN MAX VCC Supply voltage 4.5 5.5 4.5 5.5 4.5 5.5 V VIH High-level input voltage 2 2 2 V VIL Low-level input voltage 0.8 0.8 0.8 V VI Input voltage 0 VCC 0 VCC 0 VCC V VO Output voltage 0 VCC 0 VCC 0 VCC V IOH High-level output current –24 –24 –24 mA IOL Low-level output current 24 24 24 mA ∆t/∆v Input transition rise or fall rate 10 10 10 ns NOTE 4: All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
