NLVSX4373DR2G

Translators, Level Shifters Overview

The NLVSX4373DR2G is a 2-bit configurable dual-supply bidirectional auto-sensing level translator manufactured by onsemi. It operates with VCC and VL supply rails, both configurable from 1.5 V to 5.5 V, enabling voltage translation between different logic levels without requiring a directional control pin. The device features open-drain outputs with integrated 10 kΩ pullup resistors and guarantees a maximum data rate of 20 Mb/s in rail-to-rail driving configurations. It includes an enable input for tri-state operation and provides overvoltage tolerant (OVT) protection on I/O lines up to 5.5 V.

Translators, Level Shifters Feature Summary

Translators, Level Shifters Procurement Notes

Verify that the specific suffix DR2G corresponds to the SO-8 package and tape & reel shipping configuration as documented in the ordering information section. Confirm AEC-Q100 qualification status if automotive compliance is required, noting the NLV prefix indicates unique site and control change requirements. Ensure power supply decoupling capacitors are placed close to the VCC and VL pins for optimal performance.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with differing supply voltages within the 1.5 V to 5.5 V range. It is suitable for applications requiring bidirectional data transfer without complex control logic. Consider the integrated pullup resistors for simplified circuit design in open-drain scenarios. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements.
