Limiting values
[1]
Above
Tamb = 70 °C: Ptot derates linearly with 12 mW/K.
[2]
Above
Tamb = 70 °C: Ptot derates linearly with 8 mW/K.
[3]
Above
Tamb = 60 °C: Ptot derates linearly with 5.5 mW/K.
10. 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).
Table 5:
Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to
GND (ground = 0 V).
