10. Recommended operating conditions
[1] The static characteristics are guaranteed from V
CC
= 1.2 V to V
CC
= 5.5 V, but LV devices are guaranteed to
function down to V
CC
= 1.0 V (with input levels GND or V
CC
).
Table 5: Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to
GND (ground = 0 V).
