Waveshare LOGIC LEVEL CONVERTER

Features

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

How to Use

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

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