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 LT1715C is guaranteed functional over the operating range of
–40°C to 85°C.
Note 3: The LT1715C is guaranteed to meet specied performance from
0°C to 70°C. The LT1715°C is designed, characterized and expected to
meet specied performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures. The LT1715I is guaranteed to meet
specied performance from –40°C to 85°C. The LT1715H is guaranteed to
meet specied performance from –40°C to 125°C.
Note 4: Thermal resistances vary depending upon the amount of PC board
metal attached to Pin 5 of the device. θJA is specied for a 2500mm2 3/32"
FR-4 board covered with 2oz copper on both sides and with 100mm2 of
copper attached to Pin 5. Thermal performance can be improved beyond
the given specication by using a 4-layer board or by attaching more metal
area to Pin 5.
Note 5: If one input is within these common mode limits, the other input
can go outside the common mode limits and the output will be valid.
Note 6: The LT1715 comparator includes internal hysteresis. The trip
points are the input voltage needed to change the output state in each
direction. The offset voltage is dened as the average of VTRIP+ and VTRIP–,
while the hysteresis voltage is the difference of these two.
Note 7: The common mode rejection ratio is measured with VCC = 5V,
VEE = –5V and is dened as the change in offset voltage measured from
VCM = –5.1V to VCM = 3.8V, divided by 8.9V.
Note 8: The power supply rejection ratio is measured with VCM = 1V and is
dened as the worst of: the change in offset voltage from VCC = +VS = 2.7V
to VCC = +VS = 6V (with VEE = 0V) divided by 3.3V or the change in offset
voltage from VEE = 0V to VEE = –6V (with VCC = +VS = 6V) divided by 6V.
Note 9: Because of internal hysteresis, there is no small-signal region in
which to measure gain. Proper operation of internal circuity is ensured by
measuring VOH and VOL with only 20mV of overdrive.
Note 10: Maximum toggle rate is dened as the highest frequency at
which a 100mV sinusoidal input results in an error free output toggling to
greater than 4V when high and to less than 1V when low on a 5V output
supply.
Note 11: Propagation delay measurements made with 100mV steps.
Overdrive is measured relative to VTRIP±.
Note 12: tPD cannot be measured in automatic handling equipment with
low values of overdrive. The LT1715 is 100% tested with a 100mV step
and 20mV overdrive. Correlation tests have shown that tPD limits can be
guaranteed with this test.
Note 13: Propagation Delay Skew is dened as:
tSKEW = |tPDLH – tPDHL|
Note 14: Differential propagation delay is dened as the larger of the two:
ΔtPDLH = |tPDLHA – tPDLHB|
ΔtPDHL = |tPDHLA – tPDHLB|
Note 15: Package inductances combined with asynchronous activity on
the other channel can increase the output jitter. See Channel Interactions
in Applications Information. Specication above is with one channel active
only.
