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. Above 100 °C, derate linearly at a factor of 8 mW/°C. recommended operating conditions (see Note 3) MIN MAX UNIT VCC Supply voltage 2 6 V VCC = 2 V 1.5 VIH High-level input voltage VCC = 4.5 V 3.15 V VCC = 6 V 4.2 VCC = 2 V 0.5 VIL Low-level input voltage VCC = 4.5 V 1.35 V VCC = 6 V 1.8 VI Input voltage 0 VCC V VO Output voltage 0 VCC V VCC = 2 V 0 1000 tr, tf Input transition rise or fall times VCC = 4.5 V 0 500 ns VCC = 6 V 0 400 TA Operating free-air temperature –55 125 °C NOTE 3: All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
