# I2C IIC bidirectional logic level translator module 8 channels 3.3V 5V TXS0108E

> Bidirectional 8-channel logic level translator module based on the TXS0108E (CJMCU 0108), used to interface boards and sensors with different logic levels over I2C IIC or GPIO lines. Automatically converts the signal between 3.3V and 5V, with no direction control needed. VCCA connects to 3.3V, VCCB to 5V, and GND is shared between the two supplies. Input voltage: 3.3V-5V.

## Description

8-channel bidirectional converter for fast interfacing between boards and sensors with different logic levels, automatically translates signals between 3.3V and 5V on I2C IIC or GPIO lines, operates without direction control, simple VCCA 3.3V, VCCB 5V and common GND connections, ideal for prototyping and stable integrations.
8-channel bidirectional logic level converter from 3.3 to 5V and from 5 to 3.3V. CJMCU 0108.
It connects development boards and sensors operating at different logic levels by converting the signal from 3.3V to 5V and from 5V to 3.3V.
VCCA is connected to the 3.3V source
VCCB is connected to the 5V source
GND is connected common to both 3.3V and 5V sources
When Ax has a TTL 3.3V input, Bx has a TTL 5V output
When Bx has a TTL 5V input, Ax has a TTL 3.3V output
No direction control required
