Timing characTerisTics
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: A heat sink may be required to keep the junction temperature
below the absolute maximum when the output is shorted indefinitely.
Note 3: The LTC6903CMS8, LTC6904CMS8, LTC6903IMS8 and
LTC6904IMS8 are guaranteed functional over the operating temperature
range of –40°C to 85°C. The LTC6903HMS8 and LTC6904HMS8 are
guaranteed functional over the extended operating temperature range of
–40°C to 125°C.
Note 4: The LTC6903CMS8 and LTC6904CMS8 are guaranteed to meet
Typical perFormance characTerisTics

the specified performance limits over the 0°C to 70°C temperature range
and are designed, characterized and expected to meet the specified
performance from –40°C to 85°C but are not tested or QA sampled at
these temperatures. The LTC6903IMS8 and LTC6904IMS8 are guaranteed
to meet the specified performance limits over the –40°C to 85°C
temperature range. The LTC6903HMS8 and LTC6904HMS8 are guaranteed
to meet the specified performance limits over the –40°C to 125°C
temperature range.
Note 5: All values are referenced to V
Note 6: Guaranteed by design and not subject to test.
Note 7: Parts with tighter frequency accuracy are available. Consult LTC
Marketing for details.
