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. NOTE 1: The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. recommended operating conditions (see Note 2) MIN NOM MAX UNIT VCC Supply voltage 3 5 5.5 V VCC = 3 V 2.1 VIH High-level input voltage VCC = 4.5 V 3.15 V VCC = 5.5 V 3.85 VCC = 3 V 0.9 VIL Low-level input voltage VCC = 4.5 V 1.35 V VCC = 5.5 V 1.65 VI Input voltage 0 VCC V VO Output voltage 0 VCC V VCC = 3 V –4 IOH High-level output current VCC = 4.5 V –24 mA VCC = 5.5 V –24 VCC = 3 V 12 IOL Low-level output current VCC = 4.5 V 24 mA VCC = 5.5 V 24 ∆t/∆v Input transition rise or fall rate 0 10 ns / V TA Operating free-air temperature –40 85 °C NOTE 2: Unused or floating inputs must be held high or low. |
