85222AMLF Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 85222AMLF is a mixed signal translator IC in 8-SOIC packaging, designed for unidirectional signal translation between LVCMOS/LVTTL input levels and LVHSTL output levels. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. Active alternatives from onsemi, Texas Instruments, and Microchip Technology provide functional equivalence with extended operating temperature ranges and improved availability.

Substitute Part Grouping Explanation

Substitution for the 85222AMLF is determined by the following criteria:

Primary Substitution Criteria:

Translator Type: Mixed Signal
Channel Type: Unidirectional
Number of Circuits: 1
Channels per Circuit: 2
Input Signal: LVCMOS, LVTTL
Output Type: Differential
Mounting Type: Surface Mount
Package / Case: 8-SOIC or compatible 8-pin surface mount packages

Output Signal Consideration: The 85222AMLF specifies LVHSTL output, while all active substitutes provide LVPECL output. Both are differential output standards suitable for high-speed signal translation applications. LVPECL substitutes are functionally equivalent for applications requiring differential output translation from LVCMOS/LVTTL inputs.

Temperature Range Expansion: Substitute parts operate across -40°C ~ 85°C, extending the temperature capability beyond the original 0°C ~ 70°C specification, providing greater flexibility for industrial and extended-temperature applications.

Package Variants: Substitutes are available in 8-SOIC and 8-DFN packages, maintaining pin-compatible or functionally equivalent form factors for board-level integration.

Engineering Selection Recommendations

For Direct 8-SOIC Package Replacement: Select from SN65EPT22D, SN65EPT22DR, MC100EPT22DG, MC100EPT22DR2G, SY100EPT22VZG, or SY100EPT22VZG-TR. All maintain the original 8-SOIC form factor and provide ROHS3 compliance with extended operating temperature ranges.

For Compact Form Factor (8-DFN): MC100EPT22MNR4G offers a smaller 8-DFN (2x2) package footprint while maintaining functional equivalence, suitable for space-constrained applications.

For Alternate Packaging (8-VSSOP): SN65EPT22DGK and SN65EPT22DGKR provide 8-VSSOP packaging, offering a narrower body width (0.118" vs 0.154") for applications requiring reduced board real estate.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements. The original 85222AMLF carries obsolete status; substitutes are all active products with established supply chains and manufacturer support.

Inventory and Availability: Texas Instruments SN65EPT22D offers the highest inventory level (211,861 pcs), providing supply security for high-volume applications. onsemi MC100EPT22DR2G (16,353 pcs) and Microchip SY100EPT22VZG-TR (1,816 pcs) provide alternative sourcing options.

Frequently Asked Questions (FAQ)

Q: Can the 85222AMLF be directly replaced with any of these substitutes? A: Yes, all listed substitutes are functionally equivalent for applications requiring unidirectional mixed signal translation from LVCMOS/LVTTL inputs to differential outputs. The primary difference is output signal standard (LVHSTL vs LVPECL), both suitable for high-speed differential signaling. Verify your application's output signal requirements before selection.

Q: What is the difference between LVHSTL and LVPECL output standards? A: Both are differential output standards for high-speed signal transmission. LVPECL (Low Voltage Positive Emitter Coupled Logic) is the standard provided by all active substitutes. LVHSTL (Low Voltage High Speed Transceiver Logic) was the original output standard. For new designs, LVPECL substitutes are the recommended choice due to active product status and manufacturer support.

Q: Are the 8-SOIC and 8-VSSOP packages pin-compatible? A: Both packages contain 8 pins in surface mount configuration, but physical footprints differ. 8-SOIC has a body width of 0.154" (3.90mm), while 8-VSSOP has a width of 0.118" (3.00mm). PCB layout modifications are required when switching between these packages.

Q: What is the significance of the extended operating temperature range (-40°C ~ 85°C)? A: Substitute parts operate across a wider temperature range than the original 85222AMLF (0°C ~ 70°C), providing greater flexibility for industrial, automotive, and extended-temperature applications. This expanded range does not affect functionality in standard commercial temperature environments.

Q: Which substitute offers the best supply availability? A: Texas Instruments SN65EPT22D provides the highest inventory (211,861 pcs), followed by onsemi MC100EPT22DR2G (16,353 pcs). For applications requiring immediate availability, these options are recommended.

Q: Are all substitutes ROHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant, meeting current environmental and regulatory standards. The original 85222AMLF does not specify RoHS compliance status.

Q: What packaging options are available for the 100EPT22 base product? A: The 100EPT22 base product is available in three package variants: 8-SOIC (MC100EPT22DG, MC100EPT22DR2G, SY100EPT22VZG, SY100EPT22VZG-TR), 8-DFN (MC100EPT22MNR4G), and 8-VSSOP (SN65EPT22DGK, SN65EPT22DGKR). Select based on PCB layout requirements and available board space.
