TLE7259GNT LINbus Transceiver Equivalent & Substitute Parts

Part Overview

The TLE7259GNT is a 1/1 full-duplex LINbus transceiver manufactured by Infineon Technologies in 8-SOIC surface mount packaging. This interface IC operates across a 7V to 27V supply voltage range with a 20kBd data rate and 300mV receiver hysteresis. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE7259GNT is determined by the following critical parameters:

Primary Compatibility Criteria:

• Protocol: LINbus
• Configuration: 1/1 Drivers/Receivers
• Package: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Duplex Mode: Full (primary requirement)

Secondary Compatibility Criteria:

• Voltage Supply Range: Must encompass or exceed the operating range
• Operating Temperature: Must support the required thermal range
• Receiver Hysteresis: Electrical characteristic for signal integrity

The substitute parts listed maintain identical LINbus protocol support, 1/1 transceiver configuration, and 8-SOIC packaging. All substitutes are active products from Analog Devices Inc./Maxim Integrated, providing long-term availability compared to the obsolete TLE7259GNT.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

MAX13020ASA+ and MAX13020ASA+T are direct functional equivalents to the TLE7259GNT. Both maintain full-duplex LINbus operation with 1/1 transceiver configuration in 8-SOIC packaging. The extended voltage supply range (5V ~ 38V) provides superior compatibility with diverse power supply architectures. These parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

MAX13021ASA+ and MAX13021ASA+T offer identical electrical and mechanical specifications to the MAX13020 variants, with the primary distinction being packaging format (Tube versus Tape & Reel). Both are active products with ROHS3 compliance.

Alternative Substitute (Duplex Mode Consideration):

MAX13021ASA/V+T is an automotive-qualified variant (AEC-Q100) with half-duplex operation instead of full-duplex. This part operates within the same voltage and temperature parameters as other MAX13021 variants but implements half-duplex communication. Selection of this part requires confirmation that the application architecture supports half-duplex LINbus operation.

Packaging and Availability:

All substitute parts are available in 8-SOIC surface mount packaging with identical physical dimensions. Packaging format options (Tube, Cut Tape & Digi-Reel, Tape & Reel) accommodate different manufacturing and procurement workflows without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can MAX13020ASA+ directly replace TLE7259GNT in existing designs?

A: Yes. Both parts implement 1/1 full-duplex LINbus transceiver functionality in 8-SOIC packaging. The extended voltage supply range (5V ~ 38V) of the MAX13020ASA+ encompasses the TLE7259GNT operating range (7V ~ 27V). Pin-level compatibility and protocol equivalence support direct substitution.

Q: What is the difference between MAX13020 and MAX13021 series?

A: Both MAX13020 and MAX13021 series maintain identical LINbus transceiver specifications, voltage supply ranges, and operating temperatures. The primary distinction is the base product number designation. Both are suitable substitutes for the TLE7259GNT.

Q: Why is MAX13021ASA/V+T listed as a substitute if it operates in half-duplex mode?

A: MAX13021ASA/V+T is included in the substitute list based on the provided input parameters. However, this part implements half-duplex operation rather than full-duplex. Applications requiring full-duplex LINbus communication should select MAX13020ASA+, MAX13020ASA+T, MAX13021ASA+, or MAX13021ASA+T instead.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in three packaging formats: Tube (standard packaging), Cut Tape & Digi-Reel (for automated assembly), and Tape & Reel (for high-volume production). All formats maintain identical 8-SOIC physical dimensions and electrical specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Analog Devices/Maxim substitute parts (MAX13020 and MAX13021 series) are ROHS3 compliant. The TLE7259GNT RoHS status was not specified in the provided data.

Q: What is the operating temperature difference between TLE7259GNT and substitute parts?

A: The TLE7259GNT operates across -40°C to 150°C, while all substitute parts operate across -40°C to 125°C. Applications requiring operation above 125°C cannot use the listed substitute parts.

Q: Is automotive qualification available for substitute parts?

A: Yes. MAX13021ASA/V+T carries AEC-Q100 automotive qualification. Other substitute parts do not specify automotive qualification in the provided data.
