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 and all voltages are referenced

to GND unless otherwise indicated.

Note 3: The LTC4315 can level translate bus voltages ranging from

2.25V to 5.5V. In special cases, it can also level translate down to 1.4V.

See the Applications Information section for more details.

Note 4: Test performed with SDA, SCL buffers active.

Note 7: Guaranteed by design and not tested.

internal slew rate control circuitry limits the maximum bus rise rate to
