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: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
Note 3: The internal supply voltage (VCC) is generated from the greater of
the voltages on the V1 and V2 inputs. VCC = V1 for the LTC2911-5.
Note 4: Under typical operating conditions, quiescent current is drawn
from the greater of the voltages on the V1 and V2 inputs. For the
LTC2911-5 only V1 supplies the quiescent current.
Note 5: The RST and PFO output pins on the LTC2911 have internal pull-
ups to V1. However, for faster rise times or for VOH voltages greater than
V1, use an external pull-up resistor.
Note 6: The RST and PFO pull-down currents are derived from V1 and V2
except for the LTC2911-5 where the pull-down strength is derived only
from V1.
Note 7: tSU,MON is required to latch a low RST state and tSU,MON + tRST is
required to latch a high RST state.
