Features
1. 8 channels bidirectional voltage translation between different logic level, translate between Ax and Bx automatically
2. 4 pairs of power supply interfaces, supports more situations
3. Use tantalum capacitors for power filter, provides more stability
4. Voltage level: 1.8V-6V
5. Dimension: 31.6mm x 25.4mm

How to Use
In the case of translating between 3.3V and 5V system:

1. VCCA/VA connects to 3.3V power supply
2. VCCB/VB connects to 5V power supply
3. GND connects to power negative pole respectively, the two power supply should be common-grounded with each other
4. When Ax has TTL 3.3V input, Bx will get TTL 5V output
5. When Bx has TTL 5V input, Ax will get TTL 3.3V output
6. NO direction control required
