PI90LV032AW LVDS Receiver Equivalent & Substitute Parts

Part Overview

The PI90LV032AW is a 0/4 LVDS receiver interface IC manufactured by Diodes Incorporated in a 16-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement. The part operates at 400 Mbps data rate with a 3V to 3.6V supply voltage range and supports industrial temperature specifications from -40°C to 85°C. Equivalent parts are available from Texas Instruments with active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the PI90LV032AW is determined by strict equivalence across the following parameters: LVDS protocol, 0/4 receiver configuration, 400 Mbps data rate capability, 3V to 3.6V supply voltage range, -40°C to 85°C operating temperature, 16-SOIC package, and surface mount mounting type. All identified substitute parts meet these core electrical and mechanical requirements. Packaging format variations (Tube, Cut Tape & Digi-Reel, Tape & Reel) do not affect functional equivalence but influence procurement and handling logistics. The primary distinction between substitute options relates to product status (active vs. obsolete) and RoHS compliance certification level.

Engineering Selection Recommendations

All Texas Instruments substitute parts listed above maintain full electrical and mechanical compatibility with the PI90LV032AW across the specified parameter set. The primary selection criterion is product status: all substitute options carry active product status, ensuring long-term availability and manufacturing support compared to the obsolete PI90LV032AW.

For applications requiring RoHS3 compliance certification, all Texas Instruments alternatives satisfy this requirement. The original PI90LV032AW is RoHS non-compliant and should be replaced in new designs subject to RoHS regulations.

Packaging format selection depends on procurement requirements: DS90LV032ATM/NOPB and SN65LVDS32BD are supplied in Tube format; DS90LV032ATMX/NOPB is available in Cut Tape & Digi-Reel format with highest inventory availability (19,300 pcs); SN65LVDS32BDR and SN65LVDT32BDR are supplied in Tape & Reel format for automated assembly operations.

The SN65LVDS32D variant operates at 100 Mbps data rate and is suitable only for applications not requiring the full 400 Mbps capability of the original part.

Frequently Asked Questions (FAQ)

Q: Can DS90LV032ATM/NOPB and DS90LV032ATMX/NOPB be used interchangeably with PI90LV032AW?

A: Both DS90LV032 variants are direct functional equivalents. The difference between ATM and ATMX designations relates to packaging format (Tube vs. Cut Tape & Digi-Reel), not electrical performance. Both support 400 Mbps LVDS reception with identical supply voltage and temperature specifications.

Q: What is the difference between SN65LVDS32BD and SN65LVDS32BDR?

A: Both parts are electrically identical 0/4 LVDS receivers with 400 Mbps capability. The designation difference indicates packaging format: BD denotes Tube packaging, while BDR denotes Tape & Reel packaging. Selection depends on assembly process requirements.

Q: Is SN65LVDS32D a suitable replacement for PI90LV032AW?

A: SN65LVDS32D is electrically compatible but operates at 100 Mbps maximum data rate compared to the 400 Mbps specification of PI90LV032AW. This part is suitable only for applications with data rate requirements at or below 100 Mbps.

Q: Why should I replace the obsolete PI90LV032AW?

A: The PI90LV032AW is classified as obsolete, indicating discontinued manufacturing and limited future availability. Active substitute parts from Texas Instruments ensure design continuity, supply chain reliability, and compliance with current RoHS3 regulations.

Q: Are all substitute parts available in the same 16-SOIC package?

A: All substitute parts use the identical 16-SOIC (0.154", 3.90mm Width) surface mount package, ensuring direct PCB layout compatibility without redesign requirements.

Q: What is the significance of the 50 mV receiver hysteresis specification on certain parts?

A: Receiver hysteresis is specified on SN65LVDS32BD, SN65LVDS32BDR, SN65LVDS33D, and SN65LVDT32BDR. This parameter defines the input threshold differential and does not affect functional substitution for the PI90LV032AW, which does not specify this parameter in the provided data.
