Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All versions of the LTC6943 are guaranteed functional over the
operating temperature range of –40°C to 125°C. The LTC6943CGN is
guaranteed to meet 0°C to 70°C specifications and is designed,
characterized and expected to meet the specified performance from –40°C
to 85°C but it is not tested or QA sampled at these temperatures.
The LTC6943IGN is guaranteed to meet specified performance from –40°C
to 85°C. The LTC6943HGN is guaranteed to meet specified performance
from –40°C to 125°C.
Note 3: OFF leakage current at 25°C is guaranteed by design and it is not
100% tested in production.
