Data Sheet
5.0 Absolute Maximum Ratings
Over operating free-air temperature range (unless otherwise noted)
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these conditions is not recommended. Exposure to absolute maximum rated conditions
for extended periods may affect device reliability.

pF
1. Cb = capacitance of one bus line in pF.
2. The maximum t_f for the I2CDATA and I2CCLK bus lines quoted in Table 3 (300ns) is longer than the specified maximum tof for the output stages (250ns). This
allows series protection resistors (Rs) to be connected between the I2CDATA/I2CCLK pins and the I2CDATA/I2CCLK bus lines without exceeding the maximum
specified t_f.
