Renesas 85322AMILFT Mixed Signal Translator Equivalent & Substitute Parts

Part Overview

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

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 85322AMILFT are qualified based on the following electrical and mechanical parameters:

Critical Matching 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 substitute parts SN65EPT22D and SN65EPT22DR from Texas Instruments meet all critical electrical and mechanical parameters. Both parts maintain identical circuit topology, signal specifications, and physical packaging. The primary distinction between these substitutes is their product status (both active) and operating temperature range, which extends to -40°C ~ 85°C compared to the original part's 0°C ~ 70°C specification.

Parameter Comparison

Engineering Selection Recommendations

The Renesas 85322AMILFT is obsolete and no longer in active production. Texas Instruments SN65EPT22D and SN65EPT22DR are the recommended active substitutes, both maintaining full electrical and mechanical compatibility with the original design.

SN65EPT22D is supplied in tube packaging and carries 211,861 units in current inventory, providing robust supply availability for new designs and production requirements.

SN65EPT22DR is available with 1,180 units in inventory and represents an alternative packaging configuration for applications with specific procurement or logistics requirements.

Both substitute parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, matching the original part's environmental specifications. The extended operating temperature range of -40°C ~ 85°C in the Texas Instruments parts provides additional thermal margin beyond the original 0°C ~ 70°C specification, supporting deployment in broader environmental conditions.

Frequently Asked Questions (FAQ)

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

A: Yes. Both Texas Instruments parts are direct functional equivalents. They maintain identical circuit topology, signal specifications, and 8-SOIC package dimensions. The primary difference is packaging format (tube versus alternative) and extended operating temperature range.

Q: What is the difference between SN65EPT22D and SN65EPT22DR?

A: Both parts are electrically identical mixed signal translators with the same 8-SOIC package. The designation suffix indicates different packaging and distribution formats. SN65EPT22D is supplied in tube packaging, while SN65EPT22DR represents an alternative packaging configuration.

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

A: No. The Texas Instruments substitutes operate from -40°C ~ 85°C, which encompasses the original part's 0°C ~ 70°C operating range. This extended specification provides additional thermal margin and does not introduce compatibility issues.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SN65EPT22D and SN65EPT22DR are ROHS3 compliant, matching the environmental compliance status of the original 85322AMILFT.

Q: What is the moisture sensitivity level of the substitute parts?

A: Both substitute parts carry MSL Level 1 (Unlimited), identical to the original part. This indicates unlimited shelf life under normal storage conditions.
