8-CH Bi-Directional Logic Level Module Converter + Pin Header for Arduino
Description:
- 1.2V 1.8V 2.2V 2.5V 3.3V 5V logic level, easy to convert
- Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.
- Although one can use resistors to make a divider, for high speed transfers, the resistors can add a lot of slew and cause havoc that is tough to debug. For that reason, we like using 4050/74LVX245 series and similar logic to perform proper level shifting. Only problem is that they are only good in one direction which can be a problem for some specialty bi-diectional interfaces and also makes wiring a little hairy.
Features
8 channels bidirectional voltage translation between different logic level, translate between Ax and Bx automatically
Voltage level: 1.8V-6V
Dimension: 21mm x 15mm
How to Use
In the case of translating between 3.3V and 5V system:
VCCA connects to 3.3V power supply
VCCB 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
