NLSX4378FCT1G

Translators, Level Shifters Overview

The NLSX4378FCT1G is a 4-bit dual-supply level translator manufactured by onsemi. It supports bidirectional auto-sensing translation between VCC and VL rails, both configurable from 1.65 V to 5.5 V. The device guarantees a maximum data rate of 24 Mb/s in rail-to-rail configurations and features integrated 10 kΩ pullup resistors. It operates within a temperature range of -40°C to +85°C and utilizes a 12-bump MicroBump package measuring 2.02 x 1.54 mm.

Translators, Level Shifters Feature Summary

• Auto-sensing bidirectional translation without directional control pins
• Configurable dual supply rails supporting voltage step-up, step-down, or equal levels
• Integrated 10 kΩ pullup resistors optimized for open-drain applications
• Nonpreferential power-up sequencing capability

Translators, Level Shifters Applications

• I2C communication bus level shifting

Translators, Level Shifters Procurement Notes

Verify the specific suffix (e.g., FCT1G) against the official datasheet to confirm packaging details such as tape and reel quantities. Ensure the ordering part number matches the required lead-free status and backcoating specifications if applicable. Cross-reference the manufacturer's latest documentation to validate current production status and availability constraints.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits with independent power supplies where voltage levels differ or match. The absence of a directional pin simplifies PCB layout compared to traditional translators. Verify that the application timing requirements align with the specified propagation delays and rise/fall times for the chosen voltage configuration.

Translators, Level Shifters Part Context

This device belongs to the NLSX4378 family of dual-supply level shifters. It is designed to replace discrete resistor networks or complex logic gates in multi-voltage systems. The MicroBump package provides a space-saving solution for portable electronics requiring high-density interconnects.
