NLA9306MU3TAG

Translators, Level Shifters Overview

The NLA9306MU3TAG is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by onsemi. It operates with a low-voltage reference (Vref1) ranging from 0 V to 5.5 V and a high-voltage bias (Vbias_ref2) from 0 V to 5.5 V. The device features an enable input, open-drain I/O ports, and supports Standard-Mode, Fast-Mode, and Fast-Mode Plus protocols. It is housed in an UDFN8 package.

Translators, Level Shifters Feature Summary

• Provides bidirectional voltage translation between mixed-mode I2C-bus devices without requiring a direction control pin.
• Features an enable input that disconnects ports when low, creating a high-impedance state for isolation.
• Supports multiple voltage combinations including 1.0 V to 5 V and 1.8 V to 3.3 V translations.
• Offers low on-state resistance to minimize signal distortion and propagation delay.

Translators, Level Shifters Applications

• Mixed-mode I2C-bus applications connecting devices operating at different voltage levels
• SMBus interface translation between standard and fast-mode devices
• Systems requiring isolation of buses with different operating frequencies

Translators, Level Shifters Procurement Notes

Verify the specific suffix MU3TAG corresponds to the UDFN8 package configuration required for your design. Confirm RoHS compliance and lead-free status as indicated in the ordering information. Ensure the enable pin circuitry aligns with the recommended operating conditions for optimal translator performance.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting is needed for I2C or SMBus lines without complex direction logic. Consider the UDFN8 package dimensions for PCB layout constraints. Verify that the pull-up resistor values are calculated based on the specific voltage difference and desired current limits to ensure proper signal integrity.

Translators, Level Shifters Part Context

This part belongs to the NLA9306 family of voltage-level translators. It shares functional characteristics with other variants like the NLA9306DTR2G but differs in packaging. The MU3TAG suffix specifically denotes the UDFN8 case outline, distinguishing it from TSSOP-8 or US8 options within the same product line.

Translators, Level Shifters Replacement Considerations

Direct replacements include other NLA9306 variants such as NLA9306DTR2G or NLA9306USG, provided the package footprint is adapted. Cross-referencing with PCA9306 devices may be possible if electrical parameters and pinouts are compatible, though package differences must be addressed.
