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 MIN NOM MAX UNIT VCC Supply voltage 4.5 5 5.5 V VIH High-level input voltage 2 V VIL Low-level input voltage 0.8 V VI Input voltage 0 VCC V IOH High-level output current –12 mA IOL Low-level output current 24 mA ∆t/∆v Input transition rise or fall rate 5 ns / V TA Operating free-air temperature 0 70 °C |
