PI3VT3245L Equivalent & Substitute Parts

Part Overview

The PI3VT3245L is an 8x1:1 bus switch logic IC manufactured by Diodes Incorporated in a 20-TSSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Bus switches of this type are used for signal routing and multiplexing applications in digital systems requiring low-capacitance switching with minimal propagation delay.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3VT3245L is determined by strict equivalence across the following parameters: bus switch type with 8x1:1 circuit configuration, single independent circuit, single supply voltage operation, compatible voltage supply range, matching operating temperature range, surface mount technology, and 20-TSSOP package format. All identified substitutes meet these core electrical and mechanical requirements. Substitutes are grouped by manufacturer recommendation status and product lifecycle stage.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production continuity, SN74CB3T3245PWR is the primary recommended substitute. This part is manufactured by Texas Instruments, carries Active product status, maintains ROHS3 compliance, and is available in high inventory (65,780 pcs). The part operates within the required voltage supply range of 2.3V ~ 3.6V and maintains the same 20-TSSOP package footprint.

PI3VT3245-ALE serves as a secondary option from the original manufacturer Diodes Incorporated. While classified as Last Time Buy, it offers ROHS3 compliance and maintains identical electrical specifications to the obsolete PI3VT3245L. This option is suitable for designs requiring continuity with the original manufacturer.

SN74CB3T3245PW and SN74CBTLV3245APW are alternative Texas Instruments options with Last Time Buy status. Both maintain full electrical and package compatibility but have lower inventory availability compared to SN74CB3T3245PWR.

Frequently Asked Questions (FAQ)

Q: Can SN74CB3T3245PWR directly replace PI3VT3245L without PCB modifications?

A: Yes. Both parts use the 20-TSSOP package with identical pinout and footprint. No PCB layout changes are required for mechanical or electrical compatibility.

Q: What is the difference between SN74CB3T3245PWR and SN74CB3T3245PW?

A: Both parts are electrically identical 8x1:1 bus switches from Texas Instruments. The primary difference is packaging format: SN74CB3T3245PWR is supplied in Cut Tape and Digi-Reel format, while SN74CB3T3245PW is supplied in Tube packaging. SN74CB3T3245PWR has significantly higher inventory availability and Active product status.

Q: Why is PI3VT3245L marked as obsolete?

A: The original PI3VT3245L has reached end-of-life status. Equivalent parts from both Diodes Incorporated (PI3VT3245-ALE) and Texas Instruments (SN74CB3T3245 series) provide continued design support with improved compliance certifications.

Q: Are all substitute parts RoHS compliant?

A: The original PI3VT3245L is RoHS non-compliant. All identified substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What voltage supply ranges are supported?

A: The PI3VT3245L operates at 2.3V ~ 2.7V and 3V ~ 3.6V. Texas Instruments substitutes (SN74CB3T3245 series) operate at the broader 2.3V ~ 3.6V range, providing enhanced flexibility for single supply applications.

Q: Can I use these parts interchangeably in existing designs?

A: All listed substitutes maintain identical 8x1:1 bus switch functionality, single supply operation, -40°C ~ 85°C operating temperature range, and 20-TSSOP package format. Electrical compatibility is confirmed across all specified parameters.
