Use introduction, such as your microcontroller is 5V IO to communicate with the 3.3V sensor can be used to convert IO input and output voltage.
The converter uses two separate configurable power rails. The A port is designed to track VCCA.
The VCCA accepts any supply voltage between 1.2 V and 3.6 V.
The B port is designed to track VCCB. VCCB accepts 1.65 V to 5.5 V
Any supply voltage. This enables communication between any 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes
Low voltage bidirectional conversion. VCCA must not exceed VCCB.
When the output enable (OE) input is low, all outputs are placed in a high impedance state. Technical specifications for this device
Fully developed for partial power outage applications using Ioff. The Ioff circuit is responsible for deactivating the output, thus preventing destructive
The current flows back through the device when it is powered down.

Module onboard regulator chip, VCCA output voltage 1.8V 2.5V 3V 3.3V can choose the package according to their needs. The regulated output port VCCA provides the current of the external device 50MA.
The input voltage VCCB is up to 6V, which is the input conversion voltage. The input power supply needs to be greater than the conversion voltage VCCA+1V.
VCCA is based on the communication voltage of its own sensor or connected device: for example: my device is 5V and the other is 3V, so choose VCCA=3V voltage regulation.
The module supports bidirectional conversion, and the serial port ISP IO model can be accessed at will.
Wiring example, in actual use, OE can be used without being left unconnected.
VCC A The lower voltage device, VCCB is the higher voltage device, through which the signals can communicate with each other.
