3. Common Parameter Units:

️· V: Volts
️· mA: Milliamps
️· µA: Microamps
️· ns: Nanoseconds

4. Important Notes/Caveats:

️· "Note 3": This notation appears frequently and indicates that specific conditions or limitations are described elsewhere in the full documentation. It's crucial to refer to the entire datasheet for details on "Note 3".
️· Pulled-Up Outputs: Several pins (I/O, AUX1, AUX2, I/OIN, AUX1IN, AUX2IN) have internal pull-up resistors. This means that when the pin isn't actively driven low, it's pulled up to the supply voltage (VDD).
️· Current Limits: There are limits on the current that can flow into or out of various pins.
️· Timings: The document specifies timings like rise/fall times, input/output delays and pulse active times.
