IMZ 8-channel logic level converter 5V 3.3V TXS0108E YF08E

8-channel logic level converter TXS0108E

A module for bidirectional signal conversion between circuits operating at different voltages. Built on the reliable TXS0108E chip (marking YF08E), it enables safe communication between devices with logic levels from 1.2V - 3.6V and 1.8V - 5.5V. The product is ideal for ESP8266, ESP32, Arduino, Raspberry Pi, and STM32 systems.

Benefits

• Automatic direction detection - the IC adjusts signal flow direction on its own, with no need to configure extra pins manually.
• Multi-line support - up to 8 independent channels allow simultaneous conversion of multiple signals, greatly simplifying wiring.
• Broad compatibility - the converter works smoothly with the most common data interfaces, such as I2C, SPI, and UART.
• High throughput - the device handles fast data transfer at speeds up to 110 Mbps.
• Compact design - small size and very low power draw make it a good fit for energy-efficient IoT projects.

Key technical features

The converter board has pins for easy wire connection. The low-voltage side labeled LV must be powered in the 1.2V - 3.6V range, and the high-voltage side HV operates from 1.8V - 5.5V. Power-up and activation are done by driving the OE pin high. Connect a common ground between systems to the GND header.
