Pin Labeling
Pin 1 (Clock): This is the clock input pin, used to receive an external clock signal to control the operation of the potentiometer.
Pin 2 (Up/Down): This pin is used to control whether the resistance of the potentiometer increases or decreases.
Pin 3 (A): This is one terminal of the potentiometer and is usually connected to a node in the circuit.
Pin 4 (-): This is the other terminal of the potentiometer and is usually connected to another node in the circuit.
Pin 5 (Wiper): This is the sliding terminal of the potentiometer, and its position can be adjusted by an external signal.
Pin 6 (B): This is another terminal of the potentiometer and is usually connected to another node in the circuit.
Pin 7 (Chip Select): This is the chip - select pin, used to select whether to enable the operation of this chip.
Pin 8 (5VDC): This is the power - input pin, used to provide a 5V DC power supply for the chip.

The Central Graphic of the Chip
In the center of the chip, there is a simplified potentiometer graphic, indicating that this is a digital potentiometer. An arrow points to the sliding terminal of the potentiometer, indicating its adjustability.

Background and Layout
The background of the chip is gray, the pins and the labeled text are black, and the power - supply pin (Pin 8) has a red plus sign, indicating a positive power supply.
This digital potentiometer is very useful in electronic circuit design. It can precisely adjust the resistance value through digital signals and is commonly used in audio equipment, sensor calibration, power - supply management, and other applications.
