Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT8500E is guaranteed to meet performance specifications
from 0°C to 125°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT8500I is guaranteed over the full –40°C to 125°C operating junction
temperature range.
Note 3: Propagation delays, setup/hold times and hi times are measured
from 50% to 50%.
Note 4: This parameter is correlated to lab measurements and is not
subject to production testing.

denotes the specifications which apply over the full operating temperature
range, otherwise specifications are at TA = 25°C. VCC = 3.3V, and all inputs are rail-to-rail unless otherwise noted.
