SparkFun Logic Level Converter Bi-Directional (Sparkfun logic level converter )

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time.

This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

Dimensions: 0.63 x 0.52" (16.05 x 13.33mm)

WS Logic Level Converter green 8 channel (WS logic level convert green)

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
