3
SCL
Serial Bus Clock input for the I2C Serial Bus. This clock is used to clock all data
transfers into and out of the CAT51368
4
SDA
Serial Data Input/Output Bidirectional Serial Data pin used to transfer data into
and out of the CAT51368. This is an Open-Drain I/O and can be wire OR’d with
other Open-Drain (or Open Collector) I/Os.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
