Stresses beyond those listed may cause permanent damage to the device. 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. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. RECOMMENDED OPERATING CONDITIONS SYMBOL PARAMETER LIMITS UNIT SYMBOL PARAMETER MIN MAX UNIT VCC DC supply voltage 4.5 5.5 V VI Input voltage 0 VCC V VIH High-level input voltage 2.0 V VIL Low-level Input voltage 0.8 V IOH High-level output current –32 mA IOL Low-level output current 64 mA ∆t/∆v Input transition rise or fall rate 0 10 ns/V Tamb Operating free-air temperature range –40 +85 °C |
