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. Guaranteed by design, not tested in production.
Note 3. SDA, SCL high-to-low propagation delay is measured from the
beginning of a new received message telling the LTC4310 to drive its SDA,
SCL pins from high to low, to when the SDA, SCL lines have fallen below
0.5 • V

requires to process the message and pass the low to the data and clock
buffers, plus the time required by the buffers to drive their bus pins below
0.5 • V
Note 4. All currents into pins are positive, all voltages are referenced to
GND unless otherwise specified.
Note 5. Internal control circuitry prevents the rise time accelerators from
activating until the rising edge rate control circuitry is off.
