TXB0104 - 4 Channel Logic Level Converter Standard

TXB0104 logic level converter card is a card that corrects the logic level difference between circuits with different I/O voltages. It can work bidirectionally. One side of the board is called low voltage LV and the other side is called high voltage HV. An input between 1.2V and 3.6V can be made to the supply leg on the low voltage side. An input between 1.65V and 5.5V can be made to the high voltage side. On our board, the low voltage LV side is named 3.3V and the high voltage HV side is named 5V. In this way, we can make many devices operating over a wide voltage range compatible with each other. The thing to note here is that the voltage on the low voltage side is less than the level on the high voltage side (LV< HV). Eğer I/O hattında pull-up veya pull-down dirençleri kullanılacaksa bunların 50K veya üzerinde bir değerde kullanılması gerekir.

The Arduino we use today runs on 5v with a card like BasicStamp. However, many sensors, LCD displays, flash cards, etc. devices work with 3.3V. To ensure compatibility between devices, it is necessary to harmonize voltage levels with each other. In such cases, we may need to increase a 3.3V output to 5V or reduce a 5V output to 3.3V. Different methods can be tried for this. Voltage divider circuits can be made using resistors or transistor level converter circuits can be made. The easiest and smoothest way to do this is to use the TXB0108 card. Our board is designed to be breadboard compatible.
