HS2730 Level Conversion Module (5V and 3.3V IO Signal Interchange) TTL Level Compatible I2C SPI
1. Adopt TI high-speed dual power level conversion chip design.
2. Dual power supply VCCA and VCCB can support 1.65-5.5V level mutual conversion.
3.8 channels enable IO communication level shifting.
4. The A and B channel levels are controlled by VCCA and VCCB, respectively.
5. DIR signal direction control terminal: control A->B or B->A.
6. OE signal enable: chip work enable.
7. The DIR and OE signal levels are consistent with the A zone power level.
8. Ideal for level conversion between a 3.3V system and a 5V system.
Introduction to use:
This module can be applied to the communication control between different levels of single-chip microcomputers or modules. In the process of use, we only need to provide the corresponding reference power supply, the module will be equivalent to a 2-terminal different level of wire, in duplex In the communication, the direction port needs to be selected and configured. The one-way communication defaults from the control direction of zone A to zone B. By default, control and connection are not required. The direct control connection of the MCU is quite extensive and has a wide voltage conversion range.
