[2] Ptot derates linearly with 12 mW/K above 70 °C. [3] Ptot derates linearly with 8 mW/K above 70 °C. [4] Ptot derates linearly with 5.5 mW/K above 60 °C. [5] Ptot derates linearly with 4.5 mW/K above 60 °C. 8. Recommended operating conditions [1] The static characteristics are guaranteed from VCC = 1.2 V to VCC = 5.5 V, but LV devices are guaranteed to function down to VCC = 1.0 V (with input levels GND or VCC). 9.
