NLSX4373MUTAG

Translators, Level Shifters Overview

The NLSX4373MUTAG is a dual-supply bidirectional auto-sensing level translator with two configurable channels. It supports VCC and VL supply rails ranging from 1.5 V to 5.5 V, enabling translation between different voltage 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 offers overvoltage tolerant I/O lines up to 5.5 V.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'MU' corresponds to the UDFN8 package when sourcing replacements. Confirm RoHS compliance and Pb-Free status as indicated by the marking diagram. Check for automotive qualification requirements if the application demands AEC-Q100 standards, noting that the NLV prefix indicates such capability.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with mismatched supply voltages between 1.5 V and 5.5 V. It is suitable for applications requiring low bit-to-bit skew and high-speed data rates up to 20 Mb/s. Consider the UDFN8 package for space-constrained designs. Ensure the enable pin logic level is compatible with the VL supply rail for proper tri-state control.

Translators, Level Shifters Part Context
