This pin is part of the higher voltage side (e.g., 3.3V, 5V). 10 B2 Bi-directional data input/output pin for voltage level translation, similar to B1. 11 B3 Bi-directional data input/output pin for voltage level translation. 12 B4 Bi-directional data input/output pin for voltage level translation. 13 B5 Bi-directional data input/output pin for voltage level translation. 14 B6 Bi-directional data input/output pin for voltage level translation. 15 B7 Bi-directional data input/output pin for voltage level translation. 16 B8 Bi-directional data input/output pin for voltage level translation. 17 VCC Power supply pin for the device, connected to the higher voltage (e.g., 3.3V or 5V). 18 GND Ground pin for the device, connected to the common ground of the system. 19 OE Output Enable pin. When high, output drivers are enabled. When low, output drivers are disabled. 20 DIR Direction Control pin. This pin is used to control the direction of data transfer between the A and B side. When high, data flows from A to B, and vice versa when low.

4. Pin Function List Explanation (in Detail):

A1 - A8 and B1 - B8: These pins are the bidirectional data pins, and their function depends on the logic level translation between the lower voltage (e.g., 1.8V, 2.5V) and higher voltage (e.g., 3.3V, 5V) systems. The actual voltage translation takes place through these pins. VCC: This pin is the positive power supply for the device. It connects to the higher voltage side of the circuit. GND: This is the ground pin, used to reference the ground of the entire system. OE (Output Enable): This pin determines whether the device is actively driving data to the A or B pins. When high, it allows for active data transfer; when low, it disables data transfer. DIR (Direction Control): This pin is crucial for determining the direction of data flow between the A side and the B side. When it is high, data can transfer from the A side to the B side, and when low, the transfer goes from B to A.
