=='''Description'''==
In daily electronic projects, we may often encounter that the sensor cannot work normally, the project lags behind, and causes certain economic losses. This is caused by the incompatibility of the sensor level with the controller. In order to solve this problem, we have introduced a level conversion module with strong level compatibility and fast signal conversion speed.

This 8-channel level conversion module, the power supply voltage of the A port VA pin. The VA pin can accept a voltage in the range of 1.2V to 3.6V. The B port tracks the supply voltage of the VB pin. The VB pin can accept a voltage in the range of 1.65V to 5.5V. VA must be lower than or equal to VB. These two input power pins can realize any low-voltage bidirectional conversion between 1.2V, 1.8V, 2.5V, 3.3V and 5V voltage nodes. The power supply voltage can be tracked automatically. Its conversion speed can reach up to 60Mbps in push-pull applications, and can be used for level conversion of communication protocols such as I2C, UART, SPI, and OneWire.
