Overview

The TXS0108E is an 8-bit bidirectional voltage-level translator designed for interfacing devices with different logic voltage rails. It features auto-direction sensing, eliminating the need for a direction-control signal, and supports both open-drain and push-pull applications.

Why Choose This Part

The device features integrated smart pull-up resistors and requires no power-supply sequencing, simplifying power management designs. It supports a wide range of translation from 1.4V to 3.6V on the A port and 1.65V to 5.5V on the B port, provided VCCA is less than or equal to VCCB.

Applications

I2C/SMBus Level Shifting
Ideal for bridging 1.8V sensors to 3.3V or 5V controllers in open-drain configurations.
High-Speed SPI Translation
Supports push-pull data rates up to 110Mbps for high-speed serial communication between logic levels.
General Purpose IO Expansion
Translates 8 bits of GPIO between processors and peripherals operating on disparate power rails.

Getting Started

Connect VCCA and VCCB to the respective low and high voltage rails with decoupling capacitors. Pull the OE (Output Enable) pin high to enable the device; pulling it low places all I/O pins in a high-impedance state for power savings.

Also Consider

TXB0108 TITexas Instruments - Best for pure push-pull applications where high drive strength is needed, but unsuitable for open-drain buses like I2C.
