PI3B16292AE Equivalent & Substitute Parts

Part Overview

The PI3B16292AE is a 12 x 1:2 Multiplexer/Demultiplexer logic IC manufactured by Diodes Incorporated in a 56-TSSOP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Texas Instruments offers multiple active alternatives within the 74CBTLV and 74CBTLVR series that provide functional equivalence with enhanced supply voltage flexibility and continued product support.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters:

Circuit Configuration: All substitutes maintain the 12 x 1:2 multiplexer/demultiplexer architecture
Operating Temperature Range: All substitutes support -40°C ~ 85°C operation
Mounting Type: All substitutes are surface mount devices
Compliance: All substitutes are ROHS3 compliant with REACH unaffected status
Supply Voltage Compatibility: Substitute parts operate at 2.3V ~ 3.6V, which encompasses the original part's 3V ~ 3.6V range

Substitutes are grouped by package type (56-TSSOP, 56-SSOP, 56-TVSOP) and packaging format (Tube, Tape & Reel, Cut Tape & Digi-Reel). Package selection depends on assembly and procurement requirements rather than functional capability.

Engineering Selection Recommendations

Primary Substitutes (Active Status)

For new designs and production, select from the active Texas Instruments 74CBTLV series:

SN74CBTLV16292GR: Recommended for applications requiring the original 56-TFSOP package footprint. Active product status with highest inventory availability (66,080 pcs). Suitable for cut tape and Digi-Reel procurement.
SN74CBTLV16292VR: Recommended for space-constrained applications. Offers the narrowest package width (0.173", 4.40mm) while maintaining functional equivalence. Active product status with adequate inventory (2,586 pcs).
SN74CBTLV16292DL / SN74CBTLV16292DLR: Recommended for applications where the 56-BSSOP package (0.295", 7.50mm width) is acceptable. Available in both tube and tape & reel formats for flexible procurement.

Secondary Substitutes (Discontinued Status)

The 74CBTLVR series variants (SN74CBTLVR16292LR and SN74CBTLVR16292VR) are discontinued at DiGi Electronics. These parts maintain functional equivalence but should be selected only when existing inventory is available and long-term supply is not required.

Compliance Assurance

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements. Moisture sensitivity level remains at MSL 1 (Unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can SN74CBTLV16292GR directly replace PI3B16292AE in existing designs?

A: Yes. Both parts share identical 56-TFSOP package dimensions (0.240", 6.10mm width), circuit configuration (12 x 1:2), and operating temperature range (-40°C ~ 85°C). The substitute operates at 2.3V ~ 3.6V, which encompasses the original part's 3V ~ 3.6V range. No PCB redesign is required.

Q: What is the difference between 56-TSSOP and 56-SSOP packages?

A: The 56-TSSOP (56-TFSOP) is a thin shrink small outline package with 0.240" width. The 56-SSOP (56-BSSOP) is a standard shrink small outline package with 0.295" width. These are not pin-compatible and require different PCB footprints. Select based on your existing board layout.

Q: Why do some substitutes have narrower packages (56-TVSOP)?

A: The 56-TVSOP variant (0.173", 4.40mm width) offers the same functional performance in a more compact footprint. This is suitable for space-constrained applications but requires a different PCB layout than the original 56-TFSOP design.

Q: Are the 74CBTLVR series parts suitable for new production?

A: The 74CBTLVR series is discontinued at DiGi Electronics. While functionally equivalent, these parts should only be used if existing inventory is available. For new production, select from the active 74CBTLV series to ensure long-term supply continuity.

Q: What packaging formats are available for procurement?

A: Substitutes are available in three formats: Cut Tape & Digi-Reel (for automated assembly), Tape & Reel (for high-volume production), and Tube (for manual assembly or small quantities). Select based on your manufacturing process and volume requirements.

Q: Do all substitutes maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity level, matching the original part's regulatory profile.
