PI3C3245LE Equivalent & Substitute Parts

Part Overview

The PI3C3245LE is an 8 x 1:1 bus switch logic IC manufactured by Diodes Incorporated in a 20-TSSOP surface mount package. This component operates across a 2.3V to 3.6V single supply voltage range and supports operating temperatures from -40°C to 85°C. The part is currently in Last Time Buy status, indicating limited availability from the original manufacturer. Identifying qualified substitute parts ensures design continuity and supply chain flexibility for applications requiring equivalent bus switching functionality.

Substitute Part Grouping Explanation

Substitution of the PI3C3245LE is determined by strict equivalence across the following parameters: bus switch type with 8 x 1:1 circuit configuration, single independent circuit, single supply voltage operation within the 2.3V to 3.6V range, operating temperature range of -40°C to 85°C, surface mount technology, 20-TSSOP package format with 0.173" width (4.40mm), ROHS3 compliance, and MSL rating of 1. All identified substitute parts meet these criteria without exception. Substitutes differ only in manufacturer and product status designation.

Engineering Selection Recommendations

For applications currently using the PI3C3245LE, the 74CBTLV3245PGG from Renesas Electronics Corporation and ADG3245BRUZ from Analog Devices Inc. are preferred substitutes due to their Active product status, ensuring long-term availability and continued manufacturer support. Both parts maintain full parametric equivalence with identical voltage supply ranges, operating temperature specifications, and package configurations.

For designs requiring immediate component sourcing, ADG3245BRUZ offers the highest current inventory at 5896 pieces. The 74CBTLV3245PGG provides an alternative with 1979 pieces in stock and Active status from a major semiconductor manufacturer.

Texas Instruments substitutes (SN74CB3Q3245PW, SN74CB3Q3345PW, SN74CB3T3245PW, SN74CBTLV3245APW) are functionally equivalent but carry Last Time Buy designations, indicating limited future availability. These parts are suitable for existing designs but should not be selected for new long-term production programs.

All substitute parts maintain ROHS3 compliance, MSL rating of 1, and identical electrical and mechanical specifications required for direct substitution in 20-TSSOP surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the PI3C3245LE be directly replaced with any of these substitute parts?

A: Yes. All listed substitute parts are parametrically equivalent across voltage supply range (2.3V ~ 3.6V), operating temperature (-40°C ~ 85°C), circuit configuration (8 x 1:1), and package format (20-TSSOP). Direct substitution is supported without circuit modification.

Q: What is the difference between Last Time Buy and Active product status?

A: Active status indicates the manufacturer continues production and supports long-term availability. Last Time Buy status indicates the manufacturer will discontinue production after a specified date, with no future availability. For new designs, Active status parts are recommended.

Q: Are all substitute parts in the same physical package?

A: Yes. All parts use the 20-TSSOP package with 0.173" width (4.40mm). Pin-to-pin compatibility is maintained across all substitutes.

Q: Do substitute parts require different PCB layout or thermal management?

A: No. Identical package specifications ensure compatibility with existing PCB layouts, mounting processes, and thermal designs.

Q: Which substitute offers the best long-term supply security?

A: ADG3245BRUZ from Analog Devices Inc. and 74CBTLV3245PGG from Renesas Electronics Corporation both carry Active status. ADG3245BRUZ currently maintains the highest inventory level at 5896 pieces.
