Hex inverting Schmitt trigger
7. Functional description
8. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] P
tot
derates linearly with 12 mW/K above 70 C.
[3] P
tot
derates linearly with 8 mW/K above 70 C.
[4] P

9. 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
).
