DS91C176TMA LVDS Transceiver Half - Equivalent & Substitute Parts

Part Overview

The DS91C176TMA is a 1/1 transceiver half LVDS interface IC manufactured by Texas Instruments in an 8-SOIC surface mount package. This component is classified as not for new designs, indicating it has been superseded in the manufacturer's product roadmap. The part operates at 200 Mbps data rate with a 3V to 3.6V supply voltage range and supports half-duplex LVDS communication protocols. Identifying equivalent and substitute parts is necessary for legacy system maintenance, design continuity, and inventory management when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS91C176TMA is determined by strict equivalence across the following critical parameters:

• Protocol specification: LVDS half-duplex transceiver
• Driver/receiver configuration: 1/1 topology
• Data rate capability: 200 Mbps minimum
• Supply voltage range: 3V to 3.6V
• Package type: 8-SOIC surface mount
• Thermal operating range: -40°C to 85°C
• Regulatory compliance: ROHS3 and REACH status

The substitute part DS91C176TMA/NOPB meets all these criteria and represents the same base product (DS91C176) with identical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The DS91C176TMA/NOPB is a direct functional equivalent to the DS91C176TMA. Both parts share identical electrical specifications, thermal characteristics, and regulatory compliance certifications. The key distinction is product lifecycle status: the DS91C176TMA is designated as not for new designs, while the DS91C176TMA/NOPB maintains active status from Texas Instruments.

For applications requiring the DS91C176TMA, the DS91C176TMA/NOPB is the appropriate substitute. The /NOPB designation indicates lead-free, RoHS-compliant packaging without plumbum content, consistent with the ROHS3 compliance of both variants. The tube packaging format of the substitute part does not affect electrical or mechanical compatibility in PCB assembly operations.

Frequently Asked Questions (FAQ)

Q: Are DS91C176TMA and DS91C176TMA/NOPB electrically interchangeable?

A: Yes. Both parts are 1/1 LVDS half-duplex transceivers with identical data rate (200 Mbps), supply voltage range (3V to 3.6V), operating temperature range (-40°C to 85°C), and 8-SOIC package specifications. They are direct functional equivalents.

Q: What does the /NOPB suffix indicate?

A: The /NOPB designation specifies lead-free, RoHS-compliant packaging without plumbum content. Both parts maintain ROHS3 compliance and REACH unaffected status.

Q: Can I use DS91C176TMA/NOPB in existing designs originally specified for DS91C176TMA?

A: Yes. The DS91C176TMA/NOPB is a direct substitute with no design modifications required. Pin configuration, electrical performance, and package footprint are identical.

Q: What is the difference in packaging between these parts?

A: The DS91C176TMA uses standard packaging, while the DS91C176TMA/NOPB is supplied in tube format. This distinction affects only the delivery and handling method, not the component itself or its PCB assembly compatibility.

Q: Why is DS91C176TMA marked as not for new designs?

A: This designation indicates the part has been superseded in Texas Instruments' product roadmap. For new designs, Texas Instruments recommends evaluating current-generation LVDS transceiver solutions. For legacy system support and maintenance, the DS91C176TMA/NOPB remains available as an active product.
