Detailed Pin Function Explanation:

Vcc (Pin 1, 8, 13): These pins are used to provide the power supply to the device. Typically, they are connected to the positive voltage of the system (either 3.3V or 5V).

SDA1/SDA2 (Pin 2, 6, 11): The SDA pins are used for the I²C data transfer. There are two pairs of SDA pins in the device, which are used to interface with two different I²C systems or devices. SDA1 and SDA2 are used for the respective I²C systems for communication.

SCL1/SCL2 (Pin 3, 7, 12): These pins are used for the clock line of the I²C interface, used in conjunction with the SDA pins for synchronization of data communication. There are two clock lines (SCL1 and SCL2) for two different I²C systems.

GND (Pin 4, 14): The ground pins are the reference for the power supply. All circuits in the device are referenced to ground.

A0, A1, A2 (Pins 15, 16, 5): These pins are used for setting the device's I²C address. The configuration of these pins determines the address of the device in the I²C bus. These are digital inputs used to define the address.

N.C. (Pins 9, 10): These pins are not connected to any internal circuitry and can be left unconnected or floating.
