All about the product
2-way logic voltage converter 1.2-5.5V, using the TXB0104 module from Texas Instruments. Have you ever encountered a problem where the level of 5V logic signals between Arduino and 3.3V sensor or other module does not match? This converter is designed to solve this very problem. Although this can be done using a voltage divider, as the signal frequency increases, such a solution can cause difficult-to-detect problems that will not occur with this module.
This one stands out from other logic converters in that the signal conversion is bidirectional, so you can use it to both send and receive signals, which is what makes it superior to conventional logic converters. The converter automatically detects the direction of the signal.
Note: The converter has 2 power connectors, VCCA up to 3.6V, VCCB up to 5.5V. The voltage level of VCCA must not exceed the supply voltage level of VCCB (VCCA ≤ VCCB).
If at least one VCC power connector is at GND level, all connectors become in a high impedance state.
Technical data:
