Renesas 85322AMILF Mixed Signal Translator Equivalent & Substitute Parts

Part Overview

The Renesas 85322AMILF is a mixed signal translator IC designed for unidirectional signal conversion between LVCMOS/LVTTL input signals and LVPECL differential output signals. This component is packaged in an 8-SOIC surface mount package and operates across the industrial temperature range of 0°C to 70°C. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the 85322AMILF are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution validity:

Core Substitution Parameters:

• Translator Type: Mixed Signal
• Channel Type: Unidirectional
• Number of Circuits: 1
• Channels per Circuit: 2
• Input Signal Compatibility: LVCMOS, LVTTL
• Output Signal: LVPECL
• Output Type: Differential
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The identified substitute parts maintain identical functional specifications and package geometry. Both substitute parts are manufactured by Texas Instruments and carry active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Both Texas Instruments substitute parts (SN65EPT22D and SN65EPT22DR) provide direct functional equivalence to the obsolete Renesas 85322AMILF. Selection between the two Texas Instruments options is determined by packaging and supply requirements:

SN65EPT22D is supplied in tube packaging and maintains the highest inventory availability (211,861 units), making it suitable for volume production and standard procurement workflows.

SN65EPT22DR is supplied in alternative packaging with lower inventory levels (1,180 units) and carries a different ECCN classification (5A991B1 versus EAR99), which may affect export compliance considerations depending on destination markets.

Both substitute parts operate across an extended temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C), providing enhanced thermal margin for industrial and extended-temperature applications. All parts maintain ROHS3 compliance and MSL Level 1 moisture sensitivity ratings, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SN65EPT22D and SN65EPT22DR be used interchangeably with the 85322AMILF?

A: Both Texas Instruments parts maintain identical electrical specifications and 8-SOIC package geometry. Functional substitution is valid. Packaging format and ECCN classification differ between the two options and should be evaluated against procurement and export requirements.

Q: What is the primary difference between SN65EPT22D and SN65EPT22DR?

A: The parts are functionally equivalent. SN65EPT22D is supplied in tube packaging with significantly higher inventory availability. SN65EPT22DR carries a different ECCN classification (5A991B1) which may impact export compliance. Packaging format also differs between the two variants.

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: The substitute parts operate from -40°C to 85°C compared to the original 0°C to 70°C range. This represents an extended specification that maintains full compatibility with the original operating window while providing additional thermal margin for demanding applications.

Q: Are there any compliance or certification differences between the original and substitute parts?

A: All three parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status. The substitute parts carry EAR99 or 5A991B1 ECCN classifications. Verify ECCN requirements against your specific export destination before final part selection.

Q: What inventory considerations should guide part selection?

A: SN65EPT22D offers substantially higher inventory availability (211,861 units) compared to SN65EPT22DR (1,180 units), making it the preferred choice for volume production and standard lead-time requirements.
