NLSX3378FCT1G

Translators, Level Shifters Overview

The NLSX3378FCT1G is a 4-bit dual-supply bidirectional level translator featuring auto-sensing functionality without directional control pins. It supports VCC rails from 1.65 V to 4.5 V and VL rails from 1.2 V to 4.1 V, enabling translation between disparate voltage domains. The device includes integrated 10 kΩ pull-up resistors on I/O lines and an enable input for tri-state operation. It guarantees data rates up to 20 Mb/s when VL exceeds 2.5 V, with low bit-to-bit skew and overvoltage tolerant inputs.

Translators, Level Shifters Feature Summary

• Auto-sensing bidirectional translation eliminates the need for external direction control pins
• Dual independent supply rails accommodate varying logic voltage levels
• Integrated pull-up resistors simplify circuit design for open-drain applications
• Overvoltage tolerant inputs protect against signal spikes exceeding supply voltages
