PI3B3245LE Equivalent & Substitute Parts

Part Overview

The PI3B3245LE is an 8x1:1 bus switch logic IC manufactured by Diodes Incorporated in a 20-TSSOP package. This component is classified as obsolete, with 3,078 units currently in stock. Bus switches are essential for multiplexing and signal routing applications in digital systems, enabling controlled connection and isolation of multiple signal paths.

Due to the obsolete status of the PI3B3245LE, equivalent substitute parts from active product lines are necessary for new designs and long-term supply chain continuity. The substitute parts listed maintain functional equivalence through matching circuit topology, package compatibility, and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3B3245LE is determined by the following critical parameters:

• Circuit Configuration: All substitutes maintain 8x1:1 topology with 1 independent circuit
• Package Type: Primary substitutes use 20-TSSOP packaging (0.173", 4.40mm width) for direct PCB compatibility
• Voltage Supply Range: Substitutes operate within 2.3V ~ 3.6V or 3V ~ 3.6V, encompassing the original specification
• Operating Temperature: All substitutes maintain -40°C ~ 85°C range
• Mounting Type: Surface mount configuration consistent across all parts
• Compliance: ROHS3 compliance and REACH unaffected status maintained

Substitute parts are grouped into two categories: direct manufacturer variants (same manufacturer, different packaging) and cross-manufacturer equivalents (different manufacturers, functionally equivalent specifications).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PI3B3245LEX (Diodes Incorporated) is the direct equivalent with active product status, identical electrical specifications, and highest inventory availability (33,199 units). This part maintains the original 3V ~ 3.6V supply range and 20-TSSOP package footprint.

Secondary Recommendations:

For designs requiring extended voltage range compatibility (2.3V ~ 3.6V), the Renesas 74CBTLV3245 series (74CBTLV3245PGG or 74CBTLV3245PGG8) provides active product status with 20-TSSOP packaging. Both parts maintain MSL 1 rating and full compliance certifications.

For applications where package variants are acceptable, Texas Instruments SN74CB3Q3245PWR offers the highest inventory (23,200 units) in active status with 20-TSSOP packaging and extended voltage range (2.3V ~ 3.6V).

Avoid: SN74CB3Q3245PW and SN74CBTLV3245APW are designated Last Time Buy, indicating discontinued product lines with limited future availability.

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for new designs.

Frequently Asked Questions (FAQ)

Q: Can PI3B3245LE be directly replaced with PI3B3245LEX?

A: Yes. PI3B3245LEX is the active production equivalent from the same manufacturer with identical electrical specifications (3V ~ 3.6V supply, 8x1:1 circuit, 20-TSSOP package) and MSL 1 rating. No design modifications are required.

Q: What is the difference between 20-TSSOP and 20-SSOP packages?

A: 20-TSSOP has a 0.173" (4.40mm) width, while 20-SSOP has a 0.154" (3.90mm) width. These are not pin-compatible and require different PCB footprints. Verify your board layout before selecting a substitute with different package designation.

Q: Why do some substitutes specify 2.3V ~ 3.6V instead of 3V ~ 3.6V?

A: The extended lower voltage limit (2.3V vs 3V) represents a broader operating range. Parts with 2.3V ~ 3.6V are fully compatible with designs requiring 3V ~ 3.6V operation, as the original specification is a subset of the extended range.

Q: What does MSL 2 (1 Year) mean compared to MSL 1 (Unlimited)?

A: MSL 2 requires moisture bake-out procedures if the component is not used within one year of opening the sealed package. MSL 1 has no time restriction. For high-volume or long-lead applications, MSL 1 parts (PI3B3245LEX, Renesas, and most Texas Instruments variants) are preferred.

Q: Are Last Time Buy parts suitable for new designs?

A: Last Time Buy designation indicates the manufacturer will discontinue production. These parts (SN74CB3Q3245PW, SN74CBTLV3245APW) should not be selected for new designs requiring long-term supply continuity. Use Active status parts instead.

Q: Do all substitutes maintain the same pin configuration?

A: Yes. All listed substitutes maintain 8x1:1 circuit topology with identical functional pin assignments. However, package type differences (TSSOP vs SSOP vs TVSOP) require different PCB footprints despite identical pin counts.
