Overview

The TXS0104ERGYR is a 4-channel, bidirectional voltage-level translator designed for bridging communications between mismatched logic voltage domains. It features auto-direction sensing, allowing it to translate between 1.65V to 3.6V on the A-port and 2.3V to 5.5V on the B-port without a dedicated direction control pin.

Why Choose This Part

The device simplifies PCB routing because it requires no direction-control signal, automatically adapting to the data flow. It supports both open-drain and push-pull CMOS outputs with data rates up to 24Mbps, while providing integrated ESD protection on the B-port to IEC 61000-4-2 standards.

Applications

I2C Level Shifting
Translating SCL and SDA lines between a 1.8V microcontroller and 5V peripheral devices using open-drain outputs.
UART Logic Translation
Interfacing low-voltage serial ports on modern SoCs with legacy 5V sensor modules or RS-232 transceivers.
GPIO Voltage Bridging
Providing bidirectional signal level shifting for general purpose digital I/O in mixed-voltage embedded systems.

Getting Started

Place the device close to the lower-voltage processor to minimize parasitic capacitance on the VCCA side. Ensure VCCA is always less than or equal to VCCB during operation, and bypass both supply pins with 0.1uF capacitors. For evaluation, use a 14-pin VQFN-to-DIP adapter or a dedicated TXS0104E breakout board.

Also Consider

TXB0104RGYR TITexas Instruments - Choose this for pure push-pull CMOS applications requiring higher drive strength, though it is not compatible with open-drain I2C buses.
