NB6L16DR2G Equivalent & Substitute Parts

Part Overview

The NB6L16DR2G is a mixed signal translator IC manufactured by onsemi, designed for unidirectional signal translation in 8-SOIC surface mount packaging. This device accepts multiple input signal types (CML, LVCMOS, LVDS, LVNECL, LVPECL, LVTTL) and outputs differential ECL signals at 6Gbps data rate across an operating temperature range of -40°C to 85°C. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NB6L16DR2G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Translator Type: Mixed Signal
• Channel Type: Unidirectional
• Number of Circuits: 1
• Channels per Circuit: 1
• Operating Temperature Range: -40°C to 85°C
• Output Type: Differential

Compatibility Considerations: The substitute parts SN65CML100DR and SN65CML100D from Texas Instruments meet all mandatory package and functional requirements. Both are active products with confirmed inventory availability. The primary technical difference is data rate specification: the NB6L16DR2G operates at 6Gbps, while the SN65CML100 series operates at 1.5Gbps. Input signal compatibility is maintained through overlapping signal type support (CML, LVDS, LVPECL). Output signal differs (ECL vs. CML), requiring circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

SN65CML100DR (Texas Instruments) is the primary substitute option. This part maintains active product status with 2000 units in stock inventory, ensuring supply chain continuity. Full RoHS3 compliance and MSL 1 rating match the original specification. The 8-SOIC package footprint is identical, enabling direct PCB layout compatibility without redesign.

SN65CML100D (Texas Instruments) provides an alternative with 812 units available in tube packaging. This variant meets identical electrical and thermal specifications as the SN65CML100DR, with the packaging difference being the only distinction.

Both Texas Instruments substitutes are suitable for applications where the 1.5Gbps data rate specification meets system requirements. The transition from ECL to CML output signaling requires circuit-level compatibility assessment based on downstream receiver specifications.

Frequently Asked Questions (FAQ)

Q: Can SN65CML100DR and SN65CML100D be used interchangeably with NB6L16DR2G?

A: Both parts share identical electrical specifications, package dimensions, and thermal operating range. Direct substitution is possible from a mechanical and thermal standpoint. Circuit-level compatibility depends on whether the 1.5Gbps data rate and CML output signaling meet system requirements, as the original NB6L16DR2G specifies 6Gbps with ECL output.

Q: What is the difference between SN65CML100DR and SN65CML100D?

A: Both parts are functionally identical. The primary difference is packaging format: SN65CML100DR is supplied in tape and reel format, while SN65CML100D is supplied in tube packaging. Selection depends on assembly process requirements and inventory management preferences.

Q: Are the package dimensions identical across all three parts?

A: Yes. All three parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging. PCB footprints and assembly processes are directly compatible without modification.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both SN65CML100DR and SN65CML100D are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original NB6L16DR2G specifications.

Q: What input signal types do the substitute parts support?

A: The SN65CML100 series accepts CML, LVDS, and LVPECL input signals. The original NB6L16DR2G supports a broader range including LVCMOS, LVNECL, and LVTTL. Application circuits using only the overlapping signal types (CML, LVDS, LVPECL) are directly compatible.
