PI3B16210A Bus Switch 10 x 1:1 Equivalent & Substitute Parts

Part Overview

The PI3B16210A is a bus switch IC manufactured by Diodes Incorporated, configured as a 10 x 1:1 multiplexer in a 48-TSSOP package. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The PI3B16210A operates from a single 3V to 3.6V supply and functions across the industrial temperature range of -40°C to 85°C. Equivalent and substitute parts maintain functional compatibility while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3B16210A is determined by the following critical parameters:

• Circuit Configuration: 10 x 1:1 multiplexer topology
• Independent Circuits: 2 independent switch groups
• Voltage Supply Range: Minimum 2.3V to 3.6V (substitute parts support lower minimum voltage)
• Operating Temperature: -40°C to 85°C
• Mounting Type: Surface Mount
• Package Compatibility: 48-pin TSSOP, TFSOP, TVSOP, or SSOP variants

Substitute parts are grouped by package type and product status. All identified substitutes maintain the 10 x 1:1 circuit configuration and 2 independent circuits. Voltage supply ranges in substitute parts are equal to or exceed the original specification. Package variants (TSSOP, TFSOP, TVSOP, SSOP) are mechanically compatible within their respective footprint classes.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74CBTLV16210GR (Texas Instruments) or SN74CB3Q16210DGGR (Texas Instruments)

Both parts are manufactured by Texas Instruments with Active product status and ROHS3 compliance. SN74CBTLV16210GR maintains the original 48-TSSOP package footprint, ensuring direct PCB compatibility. SN74CB3Q16210DGGR offers identical electrical specifications with equivalent packaging. Both parts support the full operating temperature range and provide extended voltage supply range (2.3V to 3.6V) compared to the original PI3B16210A specification.

Secondary Recommendation: 74CBTLV16210PAG (IDT)

This part is Active status with identical package and electrical specifications. IDT manufacturing provides an alternative source for supply chain diversification.

Package Variant Alternatives: For designs permitting package substitution, SN74CBTLV16210DL, SN74CBTLV16210DLR, SN74CB3Q16210DL, and SN74CB3Q16210DLR offer 48-SSOP packaging with identical electrical performance. SN74CB3Q16210DGVR provides 48-TVSOP packaging for applications requiring reduced package width (0.173" versus 0.240").

Compliance Consideration: All recommended substitutes are ROHS3 compliant, addressing the RoHS non-compliance status of the original PI3B16210A.

Frequently Asked Questions (FAQ)

Q: Can SN74CBTLV16210GR directly replace PI3B16210A on existing PCBs?

A: Yes. Both parts use the 48-TSSOP package with identical pin assignments and electrical specifications. The footprint is mechanically and electrically compatible.

Q: What is the voltage supply difference between PI3B16210A and substitute parts?

A: The PI3B16210A operates from 3V to 3.6V. Substitute parts operate from 2.3V to 3.6V, providing a lower minimum voltage threshold. This expanded range maintains full compatibility with the original 3V to 3.6V operating window.

Q: Are there package alternatives if PCB redesign is acceptable?

A: Yes. The 48-SSOP variants (SN74CBTLV16210DL, SN74CBTLV16210DLR, SN74CB3Q16210DL, SN74CB3Q16210DLR) and 48-TVSOP variant (SN74CB3Q16210DGVR) maintain identical electrical specifications. Package selection depends on PCB layout constraints and manufacturing capabilities.

Q: Why is the PI3B16210A obsolete?

A: The PI3B16210A is classified as obsolete by Diodes Incorporated. Active equivalent parts from Texas Instruments, IDT, and Renesas Electronics provide continued availability and improved compliance status.

Q: Which substitute part offers the best supply availability?

A: SN74CBTLV16210GR (Texas Instruments) shows 4674 units in stock. SN74CB3Q16210DGGR (Texas Instruments) shows 2190 units in stock. Both represent strong inventory positions for production requirements.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant. The original PI3B16210A is RoHS non-compliant. Substitution addresses regulatory compliance requirements for new designs and updated production runs.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts are classified as MSL 1 (Unlimited), matching the original PI3B16210A specification.
