Description

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
 

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
 
Development resources: demo codes, schematic, datasheets, etc.
