SN65EPT23DR Equivalent & Substitute Parts

Part Overview

The SN65EPT23DR is a mixed signal translator IC manufactured by Texas Instruments, designed for unidirectional signal translation between LVDS/LVPECL input signals and LVCMOS/LVTTL output signals. This single-circuit, dual-channel device is housed in an 8-SOIC surface mount package and maintains an active product status with full RoHS3 compliance. Equivalent parts are necessary when primary inventory is unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits compatible substitutes that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN65EPT23DR is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Translator Type: Mixed Signal
• Channel Type: Unidirectional
• Number of Circuits: 1
• Channels per Circuit: 2
• Output Type: Non-Inverted
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Signal Compatibility Parameters:

• Input Signal must support LVDS and LVPECL
• Output Signal must support LVCMOS and LVTTL

The MC100EPT23DR2G from onsemi meets all mandatory parameters and signal compatibility requirements, making it a direct functional equivalent for the SN65EPT23DR.

Parameter Comparison

Engineering Selection Recommendations

Both the SN65EPT23DR and MC100EPT23DR2G maintain active product status with identical compliance certifications (ROHS3, REACH Unaffected, MSL 1). The MC100EPT23DR2G provides expanded input signal compatibility by supporting CML in addition to LVDS and LVPECL, while maintaining full backward compatibility with the SN65EPT23DR's specified input and output signal requirements. Both devices are suitable for applications requiring mixed signal translation in the -40°C to 85°C operating range. Selection between these parts should be based on availability, supply chain requirements, and packaging format (the MC100EPT23DR2G is supplied in Tape & Reel format).

Frequently Asked Questions (FAQ)

Q: Can the MC100EPT23DR2G directly replace the SN65EPT23DR in existing designs?

A: Yes. Both devices share identical package geometry (8-SOIC), pinout configuration, operating temperature range, and core signal translation specifications. The MC100EPT23DR2G's additional CML input support does not affect compatibility with designs using only LVDS or LVPECL inputs.

Q: Are there differences in packaging between these parts?

A: Both parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. The primary difference is supply format: the SN65EPT23DR is available in standard packaging, while the MC100EPT23DR2G is supplied in Tape & Reel (TR) format for automated assembly processes.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the SN65EPT23DR and MC100EPT23DR2G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the functional difference between these translators?

A: Both are unidirectional mixed signal translators with identical circuit count (1) and channel configuration (2 channels per circuit). The MC100EPT23DR2G accepts an additional CML input signal type, but both devices produce non-inverted LVCMOS and LVTTL outputs.

Q: Are there any temperature or reliability differences?

A: No. Both devices operate across the identical temperature range of -40°C to 85°C (TA) and carry equivalent reliability and compliance certifications.
