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: Internal clamps limit the SCL, SDA (LTC4151) and SDAI
(LTC4151-1/LTC4151-2) pins to a minimum of 5.5V. Driving these pins to
voltages beyond the clamp may damage the part. The pins can be safely
tied to higher voltages through a resistor that limits the current below
5mA.
