NLA9306USG

Translators, Level Shifters Overview

The NLA9306USG is a dual bidirectional I2C bus and SMBus voltage level translator manufactured by onsemi. It operates with VCCA ranging from 1V to 3.6V and VCCB from 1.8V to 5.5V. The device features automatic direction detection for seamless data translation without direction control pins. It supports open-drain outputs and includes an enable input. The component is housed in an 8-VFSOP package and functions within a temperature range of -55°C to +125°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional voltage translation between low-voltage (1V-3.6V) and high-voltage (1.8V-5.5V) domains for I2C and SMBus protocols.
• Features automatic direction detection, eliminating the need for external direction control pins during signal conversion.
• Includes an enable input that allows switching between active translation mode and high-impedance isolation state.

Translators, Level Shifters Applications

• Connecting mixed-mode I2C buses operating at different voltage levels
• SMBus interface translation in industrial systems
• Isolating bus segments to manage capacitance limits

Translators, Level Shifters Procurement Notes

Verify the specific suffix USG confirms the 8-VFSOP package and RoHS compliance status. Confirm current availability as product lifecycles may change. Ensure the design accommodates the specified voltage ranges and temperature ratings for the target environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing devices with mismatched I/O voltages on I2C or SMBus lines. It is suitable for applications requiring automatic direction sensing and physical isolation capabilities via the enable pin. Verify compatibility with the system's maximum bus frequency and capacitance requirements.

Translators, Level Shifters Part Context

This part belongs to the NLA9306 series, which are dual bidirectional translators based on the PCA9306 architecture. It serves as a surface-mount solution for integrating legacy or mixed-voltage components into modern low-voltage digital systems.

Translators, Level Shifters Replacement Considerations
