8 digit bi-directional 3.3V-5V/5V-3.3V logic level converter board, it can bidirectionally transfer with 8 channels between high logic voltage and low logic voltage. VCCA side voltage range: 1.2V-3.6V; VCCB side voltage range: 1.65v-5.5v; 3.3V going to VA; 5V going to VB; 3.3V going to 0E, active high enable IO recommended by a low voltage side of the IO port. High-speed shifter, tie the pin directly up to 3.3v to WORK.The level converter provide serial interfaceand is very easy to use. Widely used in the communication between 5V SCM and 3.3V device, 3.3V SCM and 5V device. It can also apply in the level conversion between MCU and SD card, MCU and iic/spi serial port devices. TXS0108E operate in both open-drain and push-pull modes, with max data throughput of about 2Mbps (open-drain) and 60Mbps (push-pull) for 3v3 to 5v translation, serial communication interface is compatible with UART/IIC/SPI port, which is easy to connect. Colour: blue Material: plastic Package Contents: 10 sets x TXS0108E 8 channel converter module Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
