NLSX3378BFCT1G

Translators, Level Shifters Overview

The NLSX3378BFCT1G is a 4-bit dual-supply level translator manufactured by onsemi. It features configurable high-side VCC (1.65 V to 4.5 V) and low-side VL (1.2 V to 4.1 V) supply rails, enabling bidirectional voltage translation between different logic levels without directional control pins. The device includes integrated 10 kΩ pullup resistors and an enable input for tri-state operation. It operates within a temperature range of -40°C to +85°C and utilizes a Bump12 package measuring 2.02 x 1.54 mm.

Translators, Level Shifters Feature Summary

• Configurable dual-supply architecture supporting independent VCC and VL rail voltages
• Bidirectional auto-sensing translation eliminating the need for directional control pins
• Integrated 10 kΩ pullup resistors on all I/O lines for open-drain compatibility
• Enable pin providing tri-state functionality to minimize power consumption

Translators, Level Shifters Applications

• I2C communication bus level shifting
• SMBus and PMBus interface translation
• Low voltage ASIC level translation in mobile devices

Translators, Level Shifters Procurement Notes

Verify the BF suffix indicates backside laminate coating when sourcing this specific variant. Confirm the Bump12 package dimensions match the required PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check that supply voltages remain within the 1.65 V to 4.5 V and 1.2 V to 4.1 V limits respectively.

Translators, Level Shifters Selection Notes

Select this component for applications requiring bidirectional translation between disparate voltage domains without complex control logic. The integrated pullups simplify circuit design for open-drain buses like I2C. Consider the small form factor for space-constrained portable electronics. Verify that the maximum data rate requirements align with the specific supply voltage configurations used.

Translators, Level Shifters Part Context

This part belongs to the NLSX3378 family of level translators from onsemi. It shares core architectural features with the standard NLSX3378FCT1G but differs in packaging specifics. The family addresses the need for seamless interoperability between modern low-voltage digital systems and legacy or higher-voltage interfaces.

Translators, Level Shifters Replacement Considerations

NLSX3378FCT1G serves as a direct functional substitute, differing primarily in the absence of the backside laminate coating found in the BF variant.
