NLSV22T244MUTAG Equivalent & Substitute Parts

Part Overview

The NLSV22T244MUTAG is a unidirectional voltage level translator manufactured by onsemi, designed for logic signal conversion between different voltage domains. This device features 2 circuits with 2 channels per circuit in a 12-UQFN (1.7x2) surface mount package. The part operates across voltage ranges of 1.6 V to 3.6 V on both VCCA and VCCB, with tri-state non-inverted output configuration and integrated over-voltage and power-off protection.

The NLSV22T244MUTAG is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system updates.

Substitute Part Grouping Explanation

Substitution eligibility for the NLSV22T244MUTAG is determined by the following critical parameters:

Translator Type: Voltage Level (required match)
Output Type: Tri-State, Non-Inverted (required match)
Voltage Operating Ranges: VCCA and VCCB compatibility within specified ranges
Operating Temperature Range: -40°C ~ 85°C (TA) (required match)
Mounting Type: Surface Mount (required match)
Compliance Standards: RoHS3 Compliant, REACH Unaffected (required match)

The SN74AVC2T45YZPR qualifies as a substitute based on these parameters. While the SN74AVC2T45YZPR operates as a bidirectional translator (compared to the unidirectional NLSV22T244MUTAG), it maintains compatibility across all critical electrical specifications, voltage ranges, output characteristics, temperature ratings, and regulatory compliance requirements. The bidirectional capability of the substitute provides functional equivalence for unidirectional applications.

Engineering Selection Recommendations

The SN74AVC2T45YZPR is qualified as a substitute for the obsolete NLSV22T244MUTAG based on the following criteria:

Electrical Compatibility: Both devices operate as voltage level translators with tri-state non-inverted outputs. The SN74AVC2T45YZPR supports a lower minimum voltage threshold (1.2 V vs. 1.6 V), providing broader voltage domain compatibility. Both devices maintain identical operating temperature ranges and output characteristics.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Product Status: The SN74AVC2T45YZPR is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete NLSV22T244MUTAG.

Package Consideration: The substitute uses an 8-DSBGA package versus the original 12-UFQFN package. PCB layout redesign is required to accommodate the different package footprint and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can the SN74AVC2T45YZPR directly replace the NLSV22T244MUTAG without circuit modifications?

A: The SN74AVC2T45YZPR is electrically compatible but requires PCB layout redesign due to different package types (8-DSBGA vs. 12-UFQFN) and pin configurations. Pin-to-pin compatibility does not exist between these packages.

Q: What is the key difference between unidirectional and bidirectional translators in this substitution?

A: The NLSV22T244MUTAG operates unidirectionally, translating signals in one direction only. The SN74AVC2T45YZPR operates bidirectionally, allowing signal translation in both directions. For unidirectional applications, the bidirectional capability of the substitute does not create incompatibility; it provides additional functionality.

Q: Are the voltage operating ranges compatible between these devices?

A: Yes. The SN74AVC2T45YZPR supports 1.2 V ~ 3.6 V on both VCCA and VCCB, which encompasses the NLSV22T244MUTAG range of 1.6 V ~ 3.6 V. The substitute operates across a broader voltage domain.

Q: What is the significance of the 500 Mbps data rate specification on the SN74AVC2T45YZPR?

A: The SN74AVC2T45YZPR is rated for 500 Mbps operation. The NLSV22T244MUTAG data rate is not specified in the provided parameters. For applications requiring high-speed signal translation, the SN74AVC2T45YZPR provides documented performance specifications.

Q: Are both devices suitable for the same operating temperature range?

A: Yes. Both the NLSV22T244MUTAG and SN74AVC2T45YZPR operate across -40°C ~ 85°C (TA), ensuring thermal compatibility across industrial and commercial temperature ranges.

Q: What compliance certifications apply to both devices?

A: Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic component manufacturing and use.
