Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT1618 is guaranteed to meet performance specifications
from 0°C to 70°C. Specifications over the – 40°C to 85°C operating
temperature range are assured by design, characterization, and correlation
with statistical process controls.
Note 3: Bias currents flow into the ISP and ISN pins.
Note 4: Switch current limit and switch VCESAT for the DD package is
guaranteed by design and/or correlation to static test.
