NLSV2T240MUTAG Equivalent & Substitute Parts

Part Overview

The NLSV2T240MUTAG is a voltage level translator IC manufactured by onsemi, designed for unidirectional signal translation between different voltage domains. This 8-pin surface mount device operates across supply voltages from 0.9 V to 4.5 V on both VCCA and VCCB channels, with integrated over-voltage and power-off protection features. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NLSV2T240MUTAG requires matching the following critical parameters:

Primary Substitution Criteria:

• Translator Type: Voltage Level
• Channel Type: Unidirectional (primary requirement)
• Number of Circuits: 1
• Channels per Circuit: 2
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Output Type: Tri-State configuration

Voltage Compatibility Constraint: The NLSV2T240MUTAG operates with VCCA and VCCB ranges of 0.9 V ~ 4.5 V. Substitute parts must support these voltage ranges or narrower ranges that fall within this specification.

Package Consideration: While the original device uses 8-UFDFN packaging, functionally equivalent alternatives may employ different 8-pin surface mount packages (8-X2SON, 8-DSBGA) provided pin configuration and electrical characteristics remain compatible.

Parameter Comparison

Engineering Selection Recommendations

SN74AVC2T244DQER (Texas Instruments): This part provides the closest functional match for unidirectional translation applications. It maintains the same circuit and channel configuration as the NLSV2T240MUTAG with active product status and full ROHS3 compliance. The voltage range (0.9 V ~ 3.6 V) is narrower than the original but covers standard logic supply voltages. The output type differs (non-inverted vs. inverted), requiring verification of signal polarity requirements in the target application. Data rate specification of 380 Mbps provides documented performance characteristics. The 8-X2SON package is a standard surface mount alternative to the original 8-UFDFN.

SN74AVC2T45YZPR (Texas Instruments): This part offers bidirectional translation capability, extending functionality beyond the original unidirectional design. It is suitable for applications requiring signal translation in both directions. The voltage range (1.2 V ~ 3.6 V) is more restrictive than the original specification. Higher data rate (500 Mbps) supports higher-speed applications. The 8-DSBGA package represents a different form factor requiring PCB layout adjustment. Product status is active with full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74AVC2T244DQER directly replace the NLSV2T240MUTAG? A: Functional replacement is possible with design verification. Both devices are unidirectional voltage level translators with identical circuit and channel counts. The key difference is output polarity (non-inverted vs. inverted), which must be evaluated against system requirements. Voltage range is narrower on the substitute (0.9 V ~ 3.6 V vs. 0.9 V ~ 4.5 V), limiting use in applications requiring the full 4.5 V upper range.

Q: Why is the SN74AVC2T45YZPR listed as a substitute if it is bidirectional? A: Bidirectional translators are functionally compatible with unidirectional applications when operated in single-direction mode. The SN74AVC2T45YZPR provides additional capability for applications that may require future bidirectional functionality. However, the narrower voltage range (1.2 V ~ 3.6 V) and different package (8-DSBGA) require design consideration.

Q: What is the impact of different output types (inverted vs. non-inverted)? A: Output polarity affects signal interpretation in the receiving circuit. The NLSV2T240MUTAG produces inverted outputs, while both Texas Instruments substitutes produce non-inverted outputs. System logic must accommodate this difference through either hardware inversion or firmware signal interpretation adjustment.

Q: Are package differences significant for substitution? A: Package differences require PCB layout modification. The original 8-UFDFN differs from the 8-X2SON (SN74AVC2T244DQER) and 8-DSBGA (SN74AVC2T45YZPR) in footprint dimensions and pin spacing. Physical board redesign is necessary for mechanical compatibility, though electrical functionality remains equivalent.

Q: What voltage range limitations apply to substitutes? A: The SN74AVC2T244DQER operates from 0.9 V ~ 3.6 V, excluding applications requiring 4.5 V operation. The SN74AVC2T45YZPR operates from 1.2 V ~ 3.6 V, further restricting low-voltage applications below 1.2 V. System supply voltage specifications must fall within substitute part ranges for valid replacement.

Q: Are all parts ROHS3 compliant? A: Yes. The NLSV2T240MUTAG and both substitute parts (SN74AVC2T244DQER and SN74AVC2T45YZPR) are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards.
