DIOLXS0102GBAEX
Overview
The LXS0102GBAEX is a 2-channel, bidirectional voltage level translator designed for interfacing modern low-voltage ICs with legacy 3.3V or 5V systems. It features automatic direction sensing, which eliminates the need for a GPIO-controlled direction pin, making it ideal for open-drain protocols like I2C and SMBus. The device supports data rates up to 24Mbps and operates with a wide voltage range from 1.65V to 5.5V.
Why Choose This Part
This translator includes integrated 10k ohm pull-up resistors, reducing external component count and PCB footprint. It supports non-preferential power-up sequencing, preventing latch-up or bus contention regardless of which rail is energized first. The WLCSP package measures only 1.89mm x 0.89mm, providing an extremely compact solution for space-constrained mobile or wearable designs.
Applications
Key Specifications
Getting Started
To use this device, connect the lower voltage rail to VCCA (1.65V to 3.6V) and the higher voltage rail to VCCB (2.3V to 5.5V). Ensure decoupling capacitors are placed close to both supply pins, and pull the Output Enable (OE) pin high to enable the device. Since it uses auto-sensing circuitry, ensure that the capacitive load on the bus stays within the limits defined for 24Mbps operation.
