Overview

The TXS0108ENMER is an 8-bit bidirectional voltage-level translator designed for interfacing devices with different logic levels. It supports data rates up to 110Mbps and operates without the need for a direction-control signal, automatically sensing the direction of data flow. This device is compatible with both open-drain and push-pull CMOS logic outputs, making it highly versatile for various digital bus standards.

Why Choose This Part

The TXS0108ENMER eliminates the need for direction-control pins, simplifying PCB routing and reducing firmware complexity. It handles a wide range of voltage levels, from 1.4V to 3.6V on the A-port and 1.65V to 5.5V on the B-port, while providing integrated ESD protection and latch-up performance exceeding 100mA.

Applications

Low-Voltage GPIO Interfacing
Bridging 1.8V microcontrollers with 3.3V or 5V sensors and peripherals.
I2C and SMBus Level Shifting
Supporting open-drain communication protocols with internal pull-up resistors for multi-master environments.
SD Card Interfacing
Translating signals between a low-voltage SoC and standard SD cards requiring 3.3V logic.
UART and SPI Communication
High-speed bidirectional level shifting for serial interfaces without needing direction-select pins.

Getting Started

When designing with the TXS0108E, ensure that VCCA is always less than or equal to VCCB. Place decoupling capacitors close to both power pins and use a pull-up resistor on the OE (Output Enable) pin to keep the I/Os in a high-impedance state during power-up or power-down.
