DS90C031BTM LVDS Driver - Equivalent & Substitute Parts

Part Overview

The DS90C031BTM is a 4/0 LVDS driver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as not for new designs, indicating it has been superseded in the manufacturer's product line. The part operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from -40°C to 85°C. Due to its discontinued status for new applications, equivalent substitute parts are necessary for ongoing system support, maintenance, and legacy design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS90C031BTM is determined by the following critical parameters: LVDS protocol compatibility, 4/0 driver/receiver configuration, 16-SOIC package format, surface mount mounting type, and operating temperature range of -40°C to 85°C. All identified substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer): DS90C031BTM/NOPB represents the active production variant of the base DS90C031 series from Texas Instruments, maintaining identical electrical specifications and packaging.

Cross-Manufacturer Equivalent: ADN4665ARZ and ADN4665ARZ-REEL7 from Analog Devices Inc. provide functional equivalence with the same driver configuration, package, and temperature range. These parts differ in supply voltage specification and data rate rating, which must be evaluated against system requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: DS90C031BTM/NOPB is the primary substitute, as it maintains active product status with Texas Instruments while preserving all electrical and mechanical specifications of the original DS90C031BTM. This part is ROHS3 compliant and carries EAR99 ECCN classification.

For Cross-Manufacturer Substitution: ADN4665ARZ and ADN4665ARZ-REEL7 from Analog Devices Inc. are functionally equivalent alternatives. Both parts are active products with ROHS3 compliance. The primary design consideration is the supply voltage specification: ADN4665 series operates at 3V to 3.6V, whereas the DS90C031 series operates at 4.5V to 5.5V. System power supply architecture must accommodate this voltage difference. The ADN4665ARZ-REEL7 variant is supplied in Tape & Reel format for high-volume production environments, while ADN4665ARZ is supplied in Tube packaging.

Packaging Consideration: All parts share identical 16-SOIC package dimensions and surface mount mounting type, ensuring PCB layout compatibility without modification.

Frequently Asked Questions (FAQ)

Q: Can DS90C031BTM/NOPB be used as a direct replacement for DS90C031BTM?

A: Yes. DS90C031BTM/NOPB is the active production equivalent of the DS90C031BTM base part number. Both maintain identical electrical specifications, package format, and operating parameters. The primary difference is product status: DS90C031BTM/NOPB is actively manufactured, while DS90C031BTM is not recommended for new designs.

Q: What is the key difference between DS90C031BTM and ADN4665ARZ?

A: The primary difference is supply voltage specification. DS90C031BTM operates at 4.5V to 5.5V, while ADN4665ARZ operates at 3V to 3.6V. Both maintain identical LVDS protocol, 4/0 driver configuration, 16-SOIC package, and -40°C to 85°C operating temperature range. System power supply compatibility must be verified before substitution.

Q: Are ADN4665ARZ and ADN4665ARZ-REEL7 electrically identical?

A: Yes. Both parts are electrically identical. The difference is packaging format: ADN4665ARZ is supplied in Tube packaging, while ADN4665ARZ-REEL7 is supplied in Tape & Reel format. Selection depends on production volume and assembly line requirements.

Q: Will substituting to ADN4665ARZ require PCB modifications?

A: No PCB layout modifications are required. All substitute parts use the identical 16-SOIC package with matching pin assignments and dimensions. However, system-level power supply architecture must be evaluated to accommodate the 3V to 3.6V supply voltage requirement of the ADN4665 series.

Q: Are all substitute parts RoHS compliant?

A: Yes. DS90C031BTM/NOPB, ADN4665ARZ, and ADN4665ARZ-REEL7 are all ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the original DS90C031BTM.
