NLSV4T244MUTAG Equivalent & Substitute Parts

Part Overview

The NLSV4T244MUTAG is a voltage level translator IC manufactured by onsemi, designed for unidirectional signal translation across different voltage domains. This 12-UQFN surface mount device operates with supply voltages ranging from 0.9 V to 4.5 V on both VCCA and VCCB, featuring tri-state non-inverted outputs with over voltage protection and power-off protection. The product is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution of the NLSV4T244MUTAG is determined by the following critical parameters:

Primary Substitution Criteria:

Translator Type: Voltage Level
Channel Type: Unidirectional
Channels per Circuit: 4
Output Type: Tri-State capability
Voltage compatibility: Supply voltage ranges must encompass or overlap with 0.9 V ~ 4.5 V
Operating Temperature: Minimum -40°C, maximum 85°C or higher
RoHS3 Compliance and MSL rating

Substitution Logic: Equivalent parts must maintain unidirectional 4-channel voltage translation functionality with tri-state output capability. Voltage supply ranges in substitute parts may extend beyond the original specification (higher maximum ratings are acceptable). Package differences are permissible provided the part is surface mount and functionally equivalent. Active product status is preferred for long-term availability.

Engineering Selection Recommendations

Primary Substitutes (Maxim Integrated MAX339x Series): The MAX3390EEUD+, MAX3390EEUD+T, MAX3391EEUD+T, MAX3392EEUD+, MAX3392EEUD+T, MAX3393EEUD+, and MAX3393EEUD+T represent the most direct functional equivalents. All maintain unidirectional 4-channel voltage translation with tri-state output capability. These parts feature extended voltage ranges (1.2 V ~ 5.5 V on VCCA, 1.65 V ~ 5.5 V on VCCB) that encompass the NLSV4T244MUTAG operating window. All are active products with ROHS3 compliance and MSL 1 rating. Operating temperature range is -40°C ~ 85°C, which covers the lower end of the original specification. The 14-TSSOP package differs from the original 12-UFQFN but maintains surface mount compatibility. Cut Tape (CT) & Digi-Reel packaging variants (EEUD+T) are available for production environments.

Secondary Substitute (Texas Instruments SN74AVC4T245RGYR): The SN74AVC4T245RGYR is a translation transceiver with 2 elements and 2 bits per element, providing 4 total channels. This part operates at 1.2 V ~ 3.6 V, which overlaps with the lower voltage range of the original part. The 3-state output capability satisfies tri-state requirements. Active product status and ROHS3 compliance are confirmed. The 16-VQFN package differs from the original specification. MSL rating of 2 (1 Year) requires controlled storage conditions compared to the original MSL 1.

Alternative Consideration (NXP HEF4104BT,652): The HEF4104BT,652 is a bus driver from NXP Semiconductors with active product status and ROHS3 compliance. Detailed electrical parameters are not fully specified in the provided data, limiting direct voltage and channel confirmation. This part is available in bulk packaging rather than cut tape or digi-reel formats.

For new designs requiring the NLSV4T244MUTAG functionality, the Maxim Integrated MAX339x series provides the highest parameter compatibility and longest-term availability assurance. The Texas Instruments SN74AVC4T245RGYR is suitable for applications operating within the 1.2 V ~ 3.6 V range.

Frequently Asked Questions (FAQ)

Q: Why is the NLSV4T244MUTAG obsolete, and what does this mean for my design? A: The NLSV4T244MUTAG is classified as obsolete by onsemi, indicating it is no longer in active production. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. New designs should transition to active equivalent parts to ensure sustained component availability and manufacturing support.

Q: Can I directly replace the NLSV4T244MUTAG with a MAX339x series part? A: The MAX3390EEUD+, MAX3391EEUD+T, MAX3392EEUD+, MAX3392EEUD+T, MAX3393EEUD+, and MAX3393EEUD+T maintain functional equivalence in unidirectional 4-channel voltage translation with tri-state outputs. Voltage supply ranges are compatible. The primary design consideration is the package change from 12-UFQFN to 14-TSSOP, which requires PCB layout modification. Operating temperature range is -40°C ~ 85°C versus the original -40°C ~ 105°C; verify this meets your application requirements.

Q: What is the difference between the MAX3390, MAX3391, MAX3392, and MAX3393 variants? A: The provided data specifies identical electrical parameters for all four variants (1.2 V ~ 5.5 V VCCA, 1.65 V ~ 5.5 V VCCB, 16 Mbps data rate, -40°C ~ 85°C operating temperature, open drain tri-state output). Functional differences between these base product numbers are not detailed in the provided specifications. Consult manufacturer datasheets for application-specific feature distinctions.

Q: Are the Cut Tape (CT) & Digi-Reel packaging variants (EEUD+T) interchangeable with Tube packaging (EEUD+)? A: Cut Tape and Tube packaging variants of the same part number contain identical die and electrical specifications. The packaging difference affects handling, storage, and automated assembly compatibility. Cut Tape (CT) & Digi-Reel format is standard for high-volume production environments, while Tube packaging is suitable for lower-volume or manual assembly operations.

Q: Does the SN74AVC4T245RGYR meet the same voltage requirements as the NLSV4T244MUTAG? A: The SN74AVC4T245RGYR operates at 1.2 V ~ 3.6 V, which overlaps with the lower portion of the NLSV4T244MUTAG range (0.9 V ~ 4.5 V). If your application requires operation below 1.2 V or above 3.6 V, the SN74AVC4T245RGYR is not suitable. The Maxim Integrated MAX339x series supports the full 1.2 V ~ 5.5 V range and is preferred for broader voltage compatibility.

Q: What is the significance of MSL 1 versus MSL 2 rating? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life under controlled storage conditions. MSL 2 requires storage at ≤30°C and ≤60% relative humidity, with a 1-year floor life limit. The NLSV4T244MUTAG and all Maxim Integrated substitutes carry MSL 1. The SN74AVC4T245RGYR carries MSL 2, requiring more stringent moisture control during storage and handling.

Q: Are all substitute parts ROHS3 compliant? A: All substitute parts listed (MAX3390EEUD+, MAX3390EEUD+T, MAX3391EEUD+T, MAX3392EEUD+, MAX3392EEUD+T, MAX3393EEUD+, MAX3393EEUD+T, SN74AVC4T245RGYR, and HEF4104BT,652) are ROHS3 compliant, matching the original NLSV4T244MUTAG specification.
