are guaranteed by design.

Note 3: Jitter is the ratio of the peak-to-peak distribution of the period to

the mean of the period. This specification is based on characterization and

is not 100% tested.

Note 4: To conform with the Logic IC Standard convention, current out of

a pin is arbitrarily given as a negative value.

Note 5: Output rise and fall times are measured between the 10% and

90% power supply levels.

Note 6: A heat sink may be required to keep the junction temperature

below the absolute maximum when the output is shorted indefinitely.

Note 7: The LTC6905C is guaranteed functional over the operating

temperature range.

Note 8: The LTC6905 is guaranteed to meet specified performance from

0°C to 70°C. The LTC6905C-XXX is designed, characterized and expected

to meet specified performance from –40°C to 85°C but is not tested or QA

sampled at these temperatures. The LTC6905I-XXX is guaranteed to meet

specified performance from –40°C to 85°C.

Note 9: The LTC6905 is optimized for the performance with a 3V power

supply voltage. Please consult LTC Marketing for parts optimized for 5V

operation.
