SN65MLVD204ADRG4 Equivalent & Substitute Parts

Part Overview

The SN65MLVD204ADRG4 is a half-duplex LVDS multipoint transceiver manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. The device operates at 3V to 3.6V supply voltage with a 100 Mbps data rate and supports operating temperatures from -40°C to 85°C. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) ensure suitability for industrial and commercial applications.

Substitute Part Grouping Explanation

Substitution of the SN65MLVD204ADRG4 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria (Must Match):

Protocol: LVDS, Multipoint
Number of Drivers/Receivers: 1/1
Duplex: Half
Package / Case: 8-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Operating Temperature Range: -40°C ~ 85°C
Voltage - Supply: 3V ~ 3.6V
Receiver Hysteresis: 25 mV
Data Rate: 100 Mbps

Parametric Equivalents (Texas Instruments SN65MLVD series) meet all primary criteria and are direct functional replacements with identical electrical and mechanical specifications.

Manufacturer Recommended Alternatives (MaxLinear SP3494EN-L and SP483EEN-L/TR) operate on different protocols (RS422/RS485) and supply voltages, making them suitable only for applications where protocol conversion or voltage adjustment is acceptable.

Engineering Selection Recommendations

Preferred Direct Replacements:

SN65MLVD204ADR and SN65MLVD200ADR are the primary substitutes for the discontinued SN65MLVD204ADRG4. Both are active products from Texas Instruments with identical electrical specifications, ROHS3 compliance, and unlimited MSL rating. SN65MLVD204ADR offers higher inventory availability (7,723 pcs) and maintains the same base product number as the original part. SN65MLVD200ADR provides an alternative with 1,900 pcs in stock and identical performance parameters.

Secondary Alternative:

SN65MLVD204DR shares identical electrical and mechanical specifications but carries a "Not For New Designs" status. This part is suitable for legacy system maintenance and repair applications where design changes are not feasible. Inventory availability is 3,460 pcs.

Protocol-Different Alternatives:

SP3494EN-L and SP483EEN-L/TR operate on RS422/RS485 protocols rather than LVDS and feature reduced data rates (2.5 Mbps and 250 kbps respectively). These parts are suitable only for applications where protocol conversion is acceptable and system architecture permits voltage adjustment (SP483EEN-L/TR requires 4.75V to 5.25V supply). Both are active products with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can SN65MLVD204ADR directly replace SN65MLVD204ADRG4 without circuit modification?

A: Yes. SN65MLVD204ADR is a parametric equivalent with identical electrical specifications, supply voltage range (3V to 3.6V), data rate (100 Mbps), package type (8-SOIC), and operating temperature range (-40°C to 85°C). No circuit modifications are required.

Q: What is the difference between SN65MLVD204ADR and SN65MLVD200ADR?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the base product number (65MLVD204 versus 65MLVD200). Selection between these parts depends on inventory availability and supply chain considerations.

Q: Why are SP3494EN-L and SP483EEN-L/TR listed as substitutes if they use different protocols?

A: These parts are manufacturer-recommended alternatives for applications where protocol conversion from LVDS to RS422/RS485 is acceptable. They are not direct functional replacements and require system-level evaluation before implementation.

Q: Is SN65MLVD204DR suitable for new designs?

A: No. SN65MLVD204DR carries a "Not For New Designs" status and is recommended only for maintenance and repair of existing systems. For new designs, use SN65MLVD204ADR or SN65MLVD200ADR.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (SN65MLVD200ADR, SN65MLVD204ADR, SN65MLVD204DR, SP3494EN-L, and SP483EEN-L/TR) are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the key difference between the MaxLinear alternatives and the Texas Instruments substitutes?

A: MaxLinear alternatives (SP3494EN-L and SP483EEN-L/TR) operate on RS422/RS485 protocols with significantly lower data rates (2.5 Mbps and 250 kbps) compared to the LVDS protocol and 100 Mbps data rate of the original part. SP483EEN-L/TR also requires a different supply voltage range (4.75V to 5.25V). These differences necessitate application-level compatibility assessment.
