Arrives
- Since MCUs are 5V devices, but most modern sensors, displays, flash cards and modes only support 3.3V, many have found that they need to perform level shift/conversion to protect 3.3V devices from 5V effects.
- This is where this cute bi-directional level converter of the chip TXB0104 comes in! The chip performs a bi-directional level conversion from almost any voltage to any voltage and automatically detects the direction.
- As the chip is a special bi-directional level converter, it has neither powerful output pins for controlling LEDs nor long cables, so it should be placed on the breadboard between two logic chips!
- We've also added 0.1µF capacitors on both sides and a 10K pull-up resistor to the output release pin so you can use it right away!
- After-sales service: Thank you for your purchase. If you have any problem, please contact us at any time. We promise you a satisfactory solution within 24 hours.
- Free 30-Day Returns
- Full Refund for Damaged or Incorrect Items
- Guaranteed Delivery or Money Back
- Secure Checkout & Fast Support

Description:
1. Although resistors can be used to build voltage dividers, resistors in high speed transmissions significantly increase conversion and cause serious damage that is difficult to fix. Therefore, we prefer to use the 4050/74LVX245 series and similar logic to perform appropriate level transitions. The only problem is that they are only effective in one direction, which can be a problem with certain special bi-directional interfaces and makes wiring a bit cumbersome.
2. This is where this cute bi-directional level converter of the chip TXB0104 comes in! The chip performs a bi-directional level conversion from almost any voltage to any voltage and automatically detects the direction.
3. The only thing the chip doesn't work well with is the i2c (because it uses strong pull-up that can confuse the automatic direction sensor) or control lines with a large number of capacitors. If you need to use pull-up resistors this is possible, but they should be at least 50K ohms - AVR/Ard's internal pull-up resistors are about 100K ohms, so all of them are fine!
