TLE7259GT LINbus Transceiver Equivalent & Substitute Parts

Part Overview

The TLE7259GT is a full-duplex LINbus transceiver manufactured by Infineon Technologies, designed for automotive and industrial communication applications. This device operates as a 1/1 transceiver with full-duplex capability, supporting LINbus protocol at 20 kBd data rate. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring LINbus interface capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE7259GT is determined by the following critical parameters:

• Protocol compatibility: LINbus interface requirement
• Transceiver configuration: 1/1 driver/receiver count
• Package compatibility: 8-SOIC form factor (0.154", 3.90mm Width)
• Mounting type: Surface mount technology
• Supply voltage range: Must accommodate automotive voltage specifications
• Operating temperature range: Industrial and automotive grade requirements

The MAX13021ASA/V+T qualifies as a substitute based on matching protocol (LINbus), transceiver configuration (1/1), and identical package format (8-SOIC). However, functional differences exist in duplex mode and electrical specifications that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The MAX13021ASA/V+T is available as an active product with ROHS3 compliance and AEC-Q100 automotive qualification, addressing supply continuity concerns for the discontinued TLE7259GT. The substitute maintains LINbus protocol compatibility, identical package format, and 1/1 transceiver configuration.

Key considerations for selection:

• Duplex mode difference: TLE7259GT operates in full-duplex mode; MAX13021ASA/V+T operates in half-duplex mode. Application architecture must support half-duplex operation.
• Supply voltage range: MAX13021ASA/V+T supports 5V ~ 38V, providing broader voltage compatibility than TLE7259GT (7V ~ 27V).
• Operating temperature: TLE7259GT supports -40°C ~ 150°C; MAX13021ASA/V+T supports -40°C ~ 125°C. Applications requiring operation above 125°C require alternative solutions.
• Regulatory compliance: MAX13021ASA/V+T meets ROHS3 and AEC-Q100 standards, suitable for automotive applications with modern compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX13021ASA/V+T directly replace TLE7259GT in existing designs?

A: Direct replacement requires verification of half-duplex operation compatibility. The MAX13021ASA/V+T operates in half-duplex mode, whereas TLE7259GT operates in full-duplex mode. Application firmware and protocol implementation must support half-duplex communication.

Q: Are the packages physically compatible?

A: Yes. Both devices use 8-SOIC (0.154", 3.90mm Width) surface mount packages with identical pin spacing and footprint requirements.

Q: What is the voltage supply difference impact?

A: MAX13021ASA/V+T supports 5V ~ 38V supply range, compared to TLE7259GT's 7V ~ 27V range. This provides greater flexibility for systems with variable supply voltages, particularly in automotive applications with transient voltage conditions.

Q: Does operating temperature range affect substitution?

A: TLE7259GT supports -40°C ~ 150°C; MAX13021ASA/V+T supports -40°C ~ 125°C. Applications requiring operation above 125°C cannot use MAX13021ASA/V+T as a substitute.

Q: What compliance certifications apply to the substitute?

A: MAX13021ASA/V+T holds AEC-Q100 automotive qualification and ROHS3 compliance, meeting modern automotive and environmental regulatory requirements. TLE7259GT is RoHS non-compliant.

Q: Are there data rate limitations with the substitute?

A: TLE7259GT specifies 20 kBd data rate. MAX13021ASA/V+T does not specify data rate in provided documentation. Verification with device datasheet is necessary for applications with specific data rate requirements.
