85222AM-01LF Mixed Signal Translator Equivalent & Substitute Parts

Part Overview

The 85222AM-01LF is a mixed signal translator IC manufactured by Renesas Electronics Corporation, designed for unidirectional signal translation between LVCMOS/LVTTL input signals and HSTL differential output signals in an 8-SOIC package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The functional requirement for unidirectional mixed signal translation with 1 circuit, 2 channels per circuit, and differential output capability defines the substitution criteria for this component category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 85222AM-01LF are selected based on the following critical parameters that must remain consistent:

• Translator Type: Mixed Signal
• Channel Type: Unidirectional
• Number of Circuits: 1
• Channels per Circuit: 2
• Input Signal Compatibility: LVCMOS, LVTTL
• Output Type: Differential
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories based on package compatibility:

Category 1: 8-SOIC Package (Direct Package Match) Parts maintaining the original 8-SOIC (0.154", 3.90mm Width) package form factor.

Category 2: Alternative Packages (Functional Equivalents) Parts with equivalent electrical functionality but different package configurations, such as 8-VSSOP or 8-MLF®, suitable for designs where package footprint flexibility exists.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (8-SOIC Package, Direct Footprint Compatibility):

MC100EPT22DG, MC100EPT22DR2G, SN65EPT22D, SN65EPT22DR, SY100EPT22VZG, and SY100EPT22VZG-TR are all active products with ROHS3 compliance and extended operating temperature ranges (-40°C ~ 85°C), providing superior thermal performance compared to the original 85222AM-01LF specification (0°C ~ 70°C). These parts maintain identical 8-SOIC package geometry and support the required unidirectional mixed signal translation with 1 circuit and 2 channels per circuit.

Alternative Package Option (Functional Equivalent):

SN65EPT22DGK provides equivalent electrical functionality in an 8-VSSOP package (0.118", 3.00mm Width), suitable for designs where package footprint optimization is acceptable. This part maintains all critical electrical parameters and active product status with ROHS3 compliance.

Compact Package Alternative (Functional Equivalent):

SY89322VMG-TR offers equivalent functionality in an 8-MLF® (2x2) package, providing a smaller footprint option for space-constrained applications while maintaining active product status and ROHS3 compliance.

All substitute parts listed are active products with current manufacturer support and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can I use SN65EPT22DGK as a direct replacement for 85222AM-01LF?

A: SN65EPT22DGK is functionally equivalent but uses an 8-VSSOP package (0.118", 3.00mm Width) instead of the original 8-SOIC package (0.154", 3.90mm Width). PCB layout modifications are required. If direct footprint compatibility is necessary, use SN65EPT22D or SN65EPT22DR instead.

Q: What is the difference between MC100EPT22DG and MC100EPT22DR2G?

A: Both parts are electrically identical mixed signal translators with 1 circuit and 2 channels per circuit. The primary difference is packaging: MC100EPT22DG is supplied in Tube packaging, while MC100EPT22DR2G is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Why do substitute parts specify LVPECL output instead of HSTL?

A: LVPECL (Low Voltage Positive Emitter Coupled Logic) and HSTL (High Speed Transceiver Logic) are both differential output standards. The substitute parts maintain the differential output type and unidirectional channel configuration required for the 85222AM-01LF application. Verify output signal compatibility with receiving circuitry in your specific design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (MC100EPT22DG, MC100EPT22DR2G, SN65EPT22D, SN65EPT22DGK, SN65EPT22DR, SY100EPT22VZG, SY100EPT22VZG-TR, and SY89322VMG-TR) are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the operating temperature difference between the original part and substitutes?

A: The 85222AM-01LF operates from 0°C ~ 70°C. All active substitute parts operate from -40°C ~ 85°C, providing extended temperature range capability suitable for industrial and automotive applications requiring broader thermal performance.

Q: Can I use SY89322VMG-TR in a design originally specified for 8-SOIC?

A: SY89322VMG-TR uses an 8-MLF® (2x2) package, which is significantly smaller than 8-SOIC. While electrically equivalent, this substitution requires complete PCB layout redesign. Use only if space constraints justify the layout modification effort.
