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 specified performance from

0°C to 70°C. The LT1715°C 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 LT1715I is guaranteed to meet

specified performance from –40°C to 85°C. The LT1715H is guaranteed to

meet specified performance from –40°C to 125°C.

Note 4: Thermal resistances vary depending upon the amount of PC board

copper attached to Pin 5. Thermal performance can be improved beyond

the given specification 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

while the hysteresis voltage is the difference of these two.

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

Note 10: Maximum toggle rate is defined 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.

low values of overdrive. The LT1715 is 100% tested with a 100mV step

guaranteed with this test.

Note 13: Propagation Delay Skew is defined as:

Note 14: Differential propagation delay is defined as the larger of the two:

Note 15: Package inductances combined with asynchronous activity on

the other channel can increase the output jitter. See Channel Interactions

in Applications Information. Specification above is with one channel active

only.
