LTC6905-XXX Series
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full specified
temperature range, otherwise specifications are at TA = 25°C or as noted. OE = DIV = V+, V+ = 2.7V to 3.6V, RL = 15k, CL = 5pF, unless
otherwise noted. All voltages are with respect to GND.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Frequency accuracy is tested with DIV = V+ (÷1). Other divide
ratios 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 LTC6905 is optimized for the performance with a 3V power
supply voltage. Refer to Typical Performance Characteristics curves in this
data sheet for additional information regarding the LTC6905 voltage
coefficient, especially between 4.5V and 5.5V. Please consult LTC
Marketing for parts optimized for 5V operation.
Note 8: The LTC6905C-XXX is guaranteed functional over the operating
temperature range and 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.
