TITXB0108
Overview
The TXB0108 is an 8-bit bidirectional voltage-level translator featuring auto-direction sensing, designed for push-pull logic applications. It operates with a VCCA range of 1.2 V to 3.6 V and a VCCB range of 1.65 V to 5.5 V, allowing seamless communication between different voltage domains without the need for a direction-control signal.
Why Choose This Part
The TXB0108 eliminates the need for a direction-control pin, simplifying PCB routing and reducing MCU pin count requirements. It includes Vcc isolation, ensuring that if either Vcc input is at GND, all outputs enter a high-impedance state, and it features integrated ESD protection exceeding JESD 22 standards.
Applications
Key Specifications
Getting Started
When designing with the TXB0108, ensure the OE (Output Enable) pin is referenced to VCCA and tied to GND through a pull-down resistor until the power supplies are stable. Note that this device is optimized for push-pull CMOS outputs; avoid using it with open-drain interfaces like I2C, which require the TXS-series translators instead.
