5 v to 3.3v level converter

8 channels bidirectional voltage translation between different logic levels, translates between Ax and Bx automatically.
4 pairs of power supply interfaces, making it more flexible.
Uses tantalum capacitors for power filtering.
Voltage level: 1.8V-6V
Dimension: 31.6mm x 25.4mm

Typical connection:

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 share a 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
